Metron –

Metron 0.4.0 with HDP 2.5 bare-metal install on Centos 6 with MariaDB for Metron REST:

Introduction

We will be installing Metron 0.4.0 with HDP 2.5 on CentOS 6. We will also install MariaDB as a database for Metron REST. Additionally, we’ll also install Apache NiFi. I installed Metron in a test environment with 3 VMs to try it out as well as a single node. I’ll try to write this guide so that the necessary steps can easily be adapted for other environments.

Environment

  • Single node: 4 CPUs, 16 GB RAM.

  • Multiple nodes:

    • 3 VMs, 2 CPUs per VM and 8 GB RAM per VM.
    • Hosts: 10.10.10.1 node1 10.10.10.2 node2 10.10.10.3 node3

Prerequisites:

  • CentOS 6

  • Add the epel repository and install tmux, vim & htop. Installing these utilities is not strictly necessary, but I install these by default for potential troubleshooting & editing of files locally):

# yum install epel-release -y
# yum update -y
# yum install vim tmux htop -y
  • Set up passwordless SSH between our nodes: If passwordless ssh has not yet been set up within the cluster, then in main node generate key:
# cat /dev/zero | ssh-keygen -q -N "" 2>/dev/null
# cd ~/.ssh
# cat id_rsa.pub >> authorized_keys
  • If you’re not installing on a single node, add this newly generated key to all the slave nodes:
ssh-copy-id -i ~/.ssh/id_rsa.pub <replace_with_node_ip>

Side note: You might have to adapt your sshd_config file and add “PermitRootLogin yes” amongst other parameters if you want passwordless root access, but that’s outside the scope of this document.

  • Increase limits for ElasticSearch and Storm on nodes where you will be installing them (if you don’t know, increase it everywhere):
# echo -e "elasticsearch - memlock unlimited\nstorm - nproc 257597" >> /etc/security/limits.conf
  • Adjust limits to secure level (link):
# ulimit -n 32768
# ulimit -u 65536
# echo -e "* - nofile 32768\n* - nproc 65536" >> /etc/security/limits.conf
  • Disable IPv6, leaving it enabled may force service to bind to IPv6 addresses only and thus resulting in inability to connect to it (source link): Disable for the running system:
# sysctl -w net.ipv6.conf.all.disable_ipv6=1
# sysctl -w net.ipv6.conf.default.disable_ipv6=1
or
# echo 1 > /proc/sys/net/ipv6/conf/all/disable_ipv6
# echo 1 > /proc/sys/net/ipv6/conf/default/disable_ipv6

To survive a reboot: Add: net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 To: /etc/sysctl.conf

# echo -e "\n# Disable IPv6\nnet.ipv6.conf.all.disable_ipv6 = 1\nnet.ipv6.conf.default.disable_ipv6 = 1" >> /etc/sysctl.conf
  • Disable Transparent Hugepage. Add “transparent_hugepage=never” to the end of the kernel line in /boot/grub/grub.conf and reboot. (Ambari demands it, do we need to comply?):
Add "transparent_hugepage=never" in the kernel line after "quiet:
"kernel /vmlinuz-2.6.32-696.3.1.el6.x86_64 ro root=/dev/mapper/vg_centos6-lv_root rd_NO_LUKS LANG=en_US.UTF-8 rd_LVM_LV=vg_centos6/lv_swap rd_NO_MD SYSFONT=latarcyrheb-sun16 crashkernel=128M rd_LVM_LV=vg_centos6/lv_root  KEYBOARDTYPE=pc KEYTABLE=us rd_NO_DM rhgb quiet"
becomes:
"kernel /vmlinuz-2.6.32-696.3.1.el6.x86_64 ro root=/dev/mapper/vg_centos6-lv_root rd_NO_LUKS LANG=en_US.UTF-8 rd_LVM_LV=vg_centos6/lv_swap rd_NO_MD SYSFONT=latarcyrheb-sun16 crashkernel=128M rd_LVM_LV=vg_centos6/lv_root  KEYBOARDTYPE=pc KEYTABLE=us rd_NO_DM rhgb quiet transparent_hugepage=never"
Afterwards, run:
# grub-install /dev/sda
  • If you do not want to mess with grub/kernel parameters, add the following to /etc/rc.local:
vim /etc/rc.local:
# Disable THP at boot time
if test -f /sys/kernel/mm/redhat_transparent_hugepage/enabled; then
  echo never > /sys/kernel/mm/redhat_transparent_hugepage/enabled
fi

if test -f /sys/kernel/mm/redhat_transparent_hugepage/defrag; then
  echo never > /sys/kernel/mm/redhat_transparent_hugepage/defrag
fi

After reboot check that changes were applied (make sure that word “never” is selected in square-brackets):

# cat /sys/kernel/mm/transparent_hugepage/enabled
always madvise [never]

Metron install pre-preparation:

  • On all nodes Install pre-requisites for Ambari:
# yum install git wget curl rpm tar unzip bzip2 wget createrepo yum-utils ntp python-pip psutils python-psutil ntp libffi-devel gcc openssl-devel npm -y
# pip install --upgrade pip
# pip install requests urllib
# pip install --upgrade setuptools
  • Install Maven 3.3.9 on main node and on Metron node install java 1.8 (if you don’t know which it is, install it everywhere):
# yum install java-1.8.0-openjdk java-1.8.0-openjdk-devel -y
  • Set path to Java 8 if it does not exist:
# export JAVA_HOME=$(readlink -f /usr/bin/java | sed "s_/jre/bin/java__")
  • Save export for future reboots:
# echo 'export JAVA_HOME=$(readlink -f /usr/bin/java | sed "s_/jre/bin/java__")' > /etc/profile.d/java_18.sh
# chmod +x /etc/profile.d/java_18.sh
# source /etc/profile.d/java_18.sh
  • Download and install Maven 3.3.9:
# wget http://apache.volia.net/maven/maven-3/3.3.9/binaries/apache-maven-3.3.9-bin.tar.gz
# tar -zxf apache-maven-3.3.9-bin.tar.gz
# mv apache-maven-3.3.9 /opt
# PATH=/opt/apache-maven-3.3.9/bin:$PATH
# echo 'export PATH=/opt/apache-maven-3.3.9/bin:$PATH' > /etc/profile.d/maven.sh
# chmod +x /etc/profile.d/maven.sh

Check whether Maven works:

# source /etc/profile.d/maven.sh
# mvn -V

You should see something similar to:

[root@base1 ~]# mvn -V

[root@base1 ~]#
  • On Ambari node install and enable docker (we will need it to build Metron mpack for Ambari):
# yum install docker-io -y
# service docker start
  • Also on your build box, install npm. This is needed to build metron-config, part of the UI.
# yum install npm -y

  • Remove ipv4 ‘localhost.localdomain’ from /etc/hosts

  • Remove ipv6 ‘localhost.localdomain’ from /etc/hosts

  • Add “127.0.0.1 localhost” to /etc/hosts

  • Install the database we will use for Metron REST:

# yum install mariadb-server mysql-connector-java -y
  • Configure a user and a database for Metron REST: If you haven’t run mysql_secure_installation after the database installation, do that first:
# service mysqld start
# /sbin/chkconfig --add mysqld
# /sbin/chkconfig --list mysqld
# /sbin/chkconfig mysqld on
# /sbin/chkconfig --list mysqld
# mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MySQL to secure it, we'll need the current
password for the root user.  If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.

Set root password? [Y/n]
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
 ... Success!


By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] n
 ... skipping.

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n]
 ... Success!
By default, MySQL comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n]
 - Dropping test database...
ERROR 1008 (HY000) at line 1: Can't drop database 'test'; database doesn't exist
 ... Failed!  Not critical, keep moving...
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n]
 ... Success!

All done!  If you've completed all of the above steps, your MySQL
installation should now be secure.

Thanks for using MySQL!


Cleaning up...
#

Build Metron code

Now we are going to start to building Metron. At the time of writing, Metron 0.4.0 was in the final stages of being released.

  • On the main node, clone the Metron repository:
# git clone https://github.com/apache/metron

If you want to make sure you’re on the 0.4.0 release branch, do:

# git clone https://github.com/apache/metron
# cd metron
# git checkout Metron_0.4.0
  • Build Metron with HDP 2.5 profile:
# cd metron
# mvn clean package -DskipTests -T 2C -P HDP-2.5.0.0,mpack
# cd metron-deployment/packaging/docker/rpm-docker
# mvn clean install -DskipTests -PHDP-2.5.0.0

If for some reason, the rpm-docker fails with the message “/bin/bash: ./build.sh: Permission denied”, try disabling selinux (“setenforce 0”) and run “mvn clean install -DskipTests -PHDP-2.5.0.0” again.

  • On all nodes, create a localrepo directory and copy the RPMs from Ambari node there:
# mkdir /localrepo
# cp -rp /root/metron/metron-deployment/packaging/docker/rpm-docker/RPMS/noarch/* /localrepo/
# createrepo /localrepo

If you’re doing a multi node install, also create localrepo on the nodes and copy the packages to the other nodes:

# ssh root@node2 mkdir /localrepo
# scp /localrepo/*\.rpm root@node2:/localrepo/.
# ssh root@node2 yum install createrepo -y
# ssh root@node2 createrepo /localrepo
  • Make sure to do the above on each node.

Fetch & create logrotate script for Hadoop Services:

# wget -O /etc/logrotate.d/metron-ambari https://raw.githubusercontent.com/apache/metron/master/metron-deployment/roles/ambari_common/templates/metron-hadoop-logrotate.yml
# sed -i 's/^  {{ hadoop_logrotate_frequency }}.*$/  daily/' /etc/logrotate.d/metron-ambari
# sed -i 's/^  rotate {{ hadoop_logrotate_retention }}.*$/  rotate 30/' /etc/logrotate.d/metron-ambari
# chmod 0644 /etc/logrotate.d/metron-ambari

Ambari 2.4 with HDP 2.5 install

Inspired by: [http://docs.hortonworks.com/HDPDocuments/Ambari-2.4.1.0/bk_ambari-installation/content/ch_Getting_Ready.html]

  • Adjust limits to secure level (inspired by link):
# ulimit -n 32768
# ulimit -u 65536
# echo -e "* - nofile 32768\n* - nproc 65536" >> /etc/security/limits.conf
  • Enable time sync, disable firewall and SElinux on every node:
# yum install ntp -y
# service ntpd start
# /sbin/chkconfig --add ntpd
# /sbin/chkconfig --list ntpd
# /sbin/chkconfig ntpd on
# /sbin/chkconfig --list ntpd
  • Disable firewall on every node:
# service iptables save
# service iptables stop
# chkconfig iptables off
  • Disable IPv6 firewall on every node:
# service ip6tables save
# service ip6tables stop
# chkconfig ip6tables off
  • Disable SElinux on every node:
# setenforce 0 (=> I know, but for the sake of simplicity, quickness & testing, I've disabled selinux.)
  • Make sure each node can resolve every other node’s hostname or add hostname of each node to /etc/hosts on every node. For example add following lines in /etc/hosts of each node: 10.10.10.1 node1 10.10.10.2 node2 10.10.10.3 node3

Where 10.10.10.1, 10.10.10.2 and 10.10.10.3 are the IPs of your nodes and node1, node2 and node3 are hostnames.

  • On main node download and setup Ambari repo (you may replace the “2.4.2.0” with a newer Ambari version number):
# wget -nv http://public-repo-1.hortonworks.com/ambari/centos6/2.x/updates/2.4.2.0/ambari.repo -O /etc/yum.repos.d/ambari.repo
# yum update -y
  • Check that it was added:
# yum repolist | grep ambari
Updates-ambari-2.4.2.0   ambari-2.4.2.0 - Updates                             12
  • Install and setup Ambari server:
# yum install ambari-server -y
# ambari-server setup -s && touch /etc/ambari-server/configured
  • Add Metron service to Ambari by running mpack command (make sure to specify correct path to mpack in –mpack=):
# ambari-server install-mpack --mpack=/root/metron/metron-deployment/packaging/ambari/metron-mpack/target/metron_mpack-0.4.0.0.tar.gz --verbose
  • Start Ambari:
# ambari-server start
  • Access the Ambari UI by going to the following URL in a web browser: http://<replace_with_master_node_ip>:8080/. You can use admin/admin as username/password. Start the Install Wizard.

Get Started page: Enter any desired cluster name.

Select Version: Make sure “Public Repository” is checked. You should also see the /localrepo directory listed.

Install Options: Specify hostnames of your nodes where Ambari cluster should be installed (all the ones you have specified in /etc/hosts) in Target Hosts. Copy content of the main node private key (/root/.ssh/id_rsa) in “Host Registration Information”. If you receive warning like below, ignore it and click OK: “The following hostnames are not valid FQDNs”

Choose Services: Select following Services: HDFS YARN + MapReduce2 Tez Hive HBase Pig Zookeeper Storm Flume Ambari Metrics Kafka Spark Zeppelin Notebook Elasticsearch Kibana Metron Slider

Assign Masters: Assign “Kafka Broker” on all nodes. Make sure move following components on one common node (Taken from previous guide, is this still necessary?): Storm UI Server Metron Indexing MySQL Server Kibana Server Elasticsearch Master Metron Parsers Metron Enrichment

Assign Slaves and Clients: select All for: DataNode NodeManager RegionServer Supervisor Client

Customize Services: Following is a list of services that need to be configured:

  • Set the “NameNode Java heap size” (namenode_heapsize) from the default 1024 MB to at least 4096 MB under HDFS -> Configs.

  • For ElasticSearch:

    • Set “zen_discovery_ping_unicast_hosts” to the IP of the node where you assigned ElasticSearch Master on the Assign Master tab.
    • Under “Advanced elastic-site”: Change “network_host” to “0.0.0.0”. Do not do this if your Metron is exposed to the public internet! Is “[ local, site ]” now.

  • Kibana:

    • Set “kibana_es_url” to http://<replace_with_elasticsearch_master_hostname>:9200. “replace_with_elasticsearch_master_hostname” is the IP of the node where you assigned ElasticSearch Master on the Assign Master tab.
    • Change kibana_default_application to “dashboard/AV-YpDmwdXwc6Ua9Muh9”

  • Metron: Set “Elasticsearch Hosts” to the IP of the node where you assigned ElasticSearch Master on the Assign Master tab.

  • Storm: You might have to increase the number of supervisor.slots.ports from the default “[6700, 6701]” to [6700, 6701, 6702, 6703, 6704] if you’re only installing a single node.

  • For metron REST use:

    Metron JDBC client path: /usr/share/java/mysql-connector-java.jar
Metron JDBC Driver: com.mysql.jdbc.Driver
Metron JDBC password: <DB PASSWORD>
Metron JDBC platform: mysql
Metron JDBC URL: jdbc:mysql://127.0.0.1:3306/<DB NAME>
Metron JDBC username: <DB USERNAME>

  • Set rest of the configuration values to recommended by Ambari or the ones you desire (like DB passwords) and perform install. In a 3 node cluster, I ended up with:

node1 node2 node3
DataNode App Timeline Server DataNode
Elasticsearch Master DataNode Elasticsearch Data Node
HBase Client DRPC Server Flume
HBase Master HBase Client HBase Client
RegionServer RegionServer RegionServer

  • Install everything. Metron REST will probably not work as we still need to add a user and the database to MySQL. At this point, make sure that all the services are up. You might have to manually start a few.

  • Configure a user for Metron REST in MySQL. On the node where you installed the Metron REST UI, do:

# mysql -u root -p
CREATE USER '<DB USERNAME>'@'localhost' IDENTIFIED BY '<DB PASSWORD>';
CREATE DATABASE IF NOT EXISTS <DB NAME>;
GRANT ALL PRIVILEGES ON <DB NAME>.* TO '<DB USERNAME>'@'localhost';

For example:

# mysql -u root -p
> CREATE USER 'metron'@'localhost' IDENTIFIED BY 'metron';
> CREATE DATABASE IF NOT EXISTS metronrest;
> GRANT ALL PRIVILEGES ON metronrest.* TO 'metron'@'localhost';
> quit
Bye
#

Add the Metron REST username and password to the metronrest database:

# mysql -u <DB USERNAME> -p
> use <DB NAME>;
> insert into users (username, password, enabled) values ('<USERNAME>','<PASSWORD>',1);
> insert into authorities (username, authority) values ('<USERNAME>', 'ROLE_USER');
> quit
Bye
#

For example, to use the username ‘metron’ with password ‘metron’, do the following:

# mysql -u metron -p
> use metronrest;
> insert into users (username, password, enabled) values ('metron','metron',1);
> insert into authorities (username, authority) values ('metron', 'ROLE_USER');
> quit
Bye
#

Make sure that all the services are up.

Install metron_pcapservice:

Miscellaneous Issues

  • There’s currently a bug in Metron 0.4.0 where Metron REST doesn’t start when restarting the Metron services. This bug was fixed in METRON-990 (https://github.com/apache/metron/pull/613/commits/1a9b19a0101ada58cb671ab224934f304df6fff8) but unfortunately, this fix didn’t make the 0.4.0 release. In order to fix this, edit the file “/etc/rc.d/init.d/metron-rest” and on line 148, change “$0 start” to “$0 start $2”.

  • I had a problem with Zeppelin after rebooting this machine and had to manually create the Zeppelin run directory:

# mkdir /var/run/zeppelin
# chown zeppelin.hadoop zeppelin/
  • Additionally, while working with Metron, I’ve noticed that at some point Zeppelin Notebook started, but immediately stopped again. In the logs, I could see “Address already in use” messages. It turns out that there was still a lingering Zeppelin process on the host. To fix it, stop Zeppelin Notebook in Ambari and then kill the latent process:
# ps aux | grep zeppelin
# kill <zeppelin_java_pid>

Afterwards, restart Zeppelin Notebook via Ambari.

  • I had a couple of issues with Elasticsearch where it wouldn’t find a master. This was fixed by doing the following. In Ambari, set the following items: “masters_also_are_datanodes” to “true” “expected_data_nodes” = “0” “gateway_recover_after_data_nodes” = “1” Restart all services. At this point, I noticed the following in :/etc/elasticsearch/elasticsearch.yml":
node:
  data: true
  master: true
  name: metron1.local

After changing this to :

node:
  data: true
  master: true
  name: metron

and restarting elasticsearch with “service elasticsearch restart”, elasticsearch started indexing.

  • Another with Elasticsearch was that I saw the following error message in Kibana:
plugin:elasticsearch     Elasticsearch is still initializing the kibana index.

This was fixed by deleting the Kibana index “.kibana”: curl -XDELETE http://localhost:9200/.kibana

Miscellaneous Services

  • Load the correct Elasticsearch template with:
curl -s -w "%{http_code}" -u <USERNAME>:<PASSWORD> -H "X-Requested-By: ambari" -X POST -d '{ "RequestInfo": { "context": "Install ES Template from REST", "command": "ELASTICSEARCH_TEMPLATE_INSTALL"},"Requests/resource_filters": [{"service_name": "METRON","component_name": "METRON_INDEXING","hosts" : "<HOSTNAME>"}]}' http://<AMBARI HOST>:8080/api/v1/clusters/<CLUSTERNAME>/requests

For example:

curl -s -w "%{http_code}" -u admin:admin -H "X-Requested-By: ambari" -X POST -d '{ "RequestInfo": { "context": "Install ES Template from REST", "command": "ELASTICSEARCH_TEMPLATE_INSTALL"},"Requests/resource_filters": [{"service_name": "METRON","component_name": "METRON_INDEXING","hosts" : "metron"}]}' http://192.168.10.10:8080/api/v1/clusters/metron/requests
  • Load Kibana Dashboard with:
curl -s -w "%{http_code}" -u <USERNAME>:<PASSWORD> -H "X-Requested-By: ambari" -X POST -d '{ "RequestInfo": { "context": "Install Kibana Dashboard from REST", "command": "KIBANA_DASHBOARD_INSTALL"},"Requests/resource_filters": [{"service_name": "METRON","component_name": "METRON_INDEXING","hosts" : "<HOSTNAME>"}]}' http://<AMBARI HOST>:8080/api/v1/clusters/<CLUSTERNAME>/requests

For example:

curl -s -w "%{http_code}" -u admin:admin -H "X-Requested-By: ambari" -X POST -d '{ "RequestInfo": { "context": "Install Kibana Dashboard from REST", "command": "KIBANA_DASHBOARD_INSTALL"},"Requests/resource_filters": [{"service_name": "METRON","component_name": "METRON_INDEXING","hosts" : "metron"}]}' http://192.168.10.10:8080/api/v1/clusters/metron/requests
  • If you installed Metron on a single node, you might have to increase the number of Storm supervisor slots from the default 2 to 5 or more. This can be done by editing the “supervisor.slots.ports” under Storm in the Ambari UI. Change:
supervisor.slots.ports: [6700, 6701]

To:

supervisor.slots.ports: [6700, 6701, 6702, 6703, 6704, 6705]

# cd /root
# wget http://apache.mirror.iweb.ca/nifi/1.2.0/nifi-1.2.0-bin.tar.gz
# tar xf nifi-1.2.0-bin.tar.gz

Before we run NiFi, we need to change the port as the default port collides with the Ambari port. To do this, we need to change the value “nifi.web.http.port=8080” to “nifi.web.http.port=8089” in the file “nifi-1.1.2/conf/nifi.properties”. Install and start NiFi afterwards:

# nifi-1.2.0/bin/nifi.sh install
# nifi-1.2.0/bin/nifi.sh start

Exposed Interfaces

In the end, you’ll end up with a bunch of exposed UIs:
