Metron REST

From Source

1. Package the application with Maven:

   mvn clean package
   

2. Untar the archive in the $METRON_HOME directory. The directory structure will look like:

   config
     rest_application.yml
   bin
     metron-rest
   lib
     metron-rest-$METRON_VERSION.jar
   

3. Copy the $METRON_HOME/bin/metron-rest script to /etc/init.d/metron-rest

From Package Manager

1. Deploy the RPM at /metron/metron-deployment/packaging/docker/rpm-docker/target/RPMS/noarch/metron-rest-$METRON_VERSION-*.noarch.rpm

2. Install the RPM with:

   rpm -ih metron-rest-$METRON_VERSION-*.noarch.rpm
   

REQUIRED

No optional parameter has a default.

Optional - With Defaults

Optional - Blank Defaults

These are set in the /etc/default/metron file.

Logging

Logging for the REST application can be configured in Ambari. Log levels can be changed at the root, package and class level:

1. Navigate to Services > Metron > Configs > REST and locate the Metron Spring options setting.

2. Logging configuration is exposed through Spring properties as explained here.

3. The root logging level defaults to ERROR but can be changed to INFO by adding --logging.level.root=INFO to the Metron Spring options setting.

4. The Metron REST logging level can be changed to INFO by adding --logging.level.org.apache.metron.rest=INFO.

5. HTTP request and response logging can be enabled by adding --logging.level.org.springframework.web.filter.CommonsRequestLoggingFilter=DEBUG --logging.level.org.apache.metron.rest.web.filter.ResponseLoggingFilter=DEBUG.

Spring Profiles

The REST application comes with a few Spring Profiles to aid in testing and development.

Setting active profiles is done with the METRON_SPRING_PROFILES_ACTIVE variable. For example, set this variable in /etc/default/metron to configure the REST application for the Vagrant environment and add a test user:

METRON_SPRING_PROFILES_ACTIVE="vagrant,dev"

Kerberos

Metron REST can be configured for a cluster with Kerberos enabled. A client JAAS file is required for Kafka and Zookeeper and a Kerberos keytab for the metron user principal is required for all other services. Configure these settings in the /etc/default/metron file:

SECURITY_ENABLED=true
METRON_JVMFLAGS="-Djava.security.auth.login.config=$METRON_HOME/client_jaas.conf"
METRON_PRINCIPAL_NAME="metron@EXAMPLE.COM"
METRON_SERVICE_KEYTAB="/etc/security/keytabs/metron.keytab"

LDAP Authentication

Metron REST can be configured to use LDAP for authentication and roles. Use the following steps to enable LDAP.

1. In Ambari, go to Metron > Config > Security > Roles

   • Set “User Role Name” to the name of the role at the authentication provider that provides user level access to Metron.

   • Set “Admin Role Name” to the name of the role at the authentication provider that provides administrative access to Metron.

2. In Ambari, go to Metron > Config > Security > LDAP

   • Turn on LDAP using the toggle.

   • Set “LDAP URL” to your LDAP instance. For example, ldap://<host>:<port>.

   • Set “Bind User” to the name of the bind user. For example, cn=admin,dc=apache,dc=org.

   • Set the “Bind User Password”

   • Other fields may be required depending on your LDAP configuration.

3. Save the changes and restart the required services.

By default, configuration will default to matching Knox’s Demo LDAP for convenience. This should only be used for development purposes. Manual instructions for setting up demo LDAP and finalizing configuration (e.g. setting up the user LDIF file) can be found in the Development README.

keytool -import -alias <alias> -file <certificate> -keystore <keystore_file> -storepass <password>

dn: cn=admin,ou=groups,dc=hadoop,dc=apache,dc=org
objectclass:top
objectclass: groupofnames
cn: admin
description:admin group
member: uid=admin,ou=people,dc=hadoop,dc=apache,dc=org

dn: cn=user,ou=groups,dc=hadoop,dc=apache,dc=org
objectclass:top
objectclass: groupofnames
cn: user
description: user group
member: uid=sam,ou=people,dc=hadoop,dc=apache,dc=org

JDBC Authentication

The REST application persists data in a relational database and requires a dedicated database user and database (see https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-sql.html for more detail).
Spring uses Hibernate as the default ORM framework but another framework is needed becaused Hibernate is not compatible with the Apache 2 license. For this reason Metron uses EclipseLink. See the Spring Data JPA - EclipseLink project for an example on how to configure EclipseLink in Spring.

The metron-rest module uses Spring Security for authentication and stores user credentials in the relational database configured above. The required tables are created automatically the first time the application is started so that should be done first. For example (continuing the MySQL example above), users can be added by connecting to MySQL and running:

use metronrest;
insert into users (username, password, enabled) values ('your_username','your_password',1);
insert into authorities (username, authority) values ('your_username', 'ROLE_USER');

Development

The REST application comes with embedded database support for development purposes.

For example, edit these variables in /etc/default/metron before starting the application to configure H2:

METRON_JDBC_DRIVER="org.h2.Driver"
METRON_JDBC_URL="jdbc:h2:file:~/metrondb"
METRON_JDBC_USERNAME="root"
METRON_JDBC_PLATFORM="h2"

Production

The REST application should be configured with a production-grade database outside of development.

metron-docker

Start the metron-docker environment. Build the metron-rest module and start it with the Spring Boot Maven plugin:

mvn clean package
mvn spring-boot:run -Drun.profiles=docker,dev

The metron-rest application will be available at http://localhost:8080/swagger-ui.html#/.

Full Dev

Start the development environment. Build the metron-rest module and start it with the Spring Boot Maven plugin:

mvn clean package
mvn spring-boot:run -Drun.profiles=vagrant,dev

The metron-rest application will be available at http://localhost:8080/swagger-ui.html#/.

To run the application locally on the Full Dev host (node1), follow the Installation instructions above. Then set the METRON_SPRING_PROFILES_ACTIVE variable in /etc/default/metron:

METRON_SPRING_PROFILES_ACTIVE="vagrant,dev"

and start the application:

service metron-rest start

In a cluster with Kerberos enabled, update the security settings in /etc/default/metron. Security is disabled by default in the vagrant Spring profile so that setting must be overriden with the METRON_SPRING_OPTIONS variable:

METRON_SPRING_PROFILES_ACTIVE="vagrant,dev"
METRON_JVMFLAGS="-Djava.security.auth.login.config=$METRON_HOME/client_jaas.conf"
METRON_SPRING_OPTIONS="--kerberos.enabled=true"

The metron-rest application will be available at http://node1:8082/swagger-ui.html#/.
