MySQL Data Store for Oozie

Follow these steps to configure Oozie to use a MySQL database as the Oozie data store (instead of the default Apache Derby database). The MySQL database can also be used to support high availability (HA).
  1. Using the mysql command-line tool, create a MySQL database, user, and password for the Oozie user. For example:
    mysql> create database oozie;
    mysql> grant all privileges on oozie.* to '<oozie-user>'@'%' identified by '<oozie-passwd>';
  2. Stop the Oozie server:
    maprcli node services -name oozie -action stop -nodes <node-list>
  3. Set the following JPAService properties in the oozie-site.xml file: Note: In the JDBC URL property, use the correct hostname (where MySQL is running).
    <property>
        <name>oozie.service.JPAService.jdbc.driver</name>
        <value>com.mysql.jdbc.Driver</value>
    </property>
    <property>
        <name>oozie.service.JPAService.jdbc.url</name>
        <value>jdbc:mysql://localhost:3306/oozie</value>
        </property>
    <property>
        <name>oozie.service.JPAService.jdbc.username</name>
        <value>oozie</value>
    </property>
    <property>
        <name>oozie.service.JPAService.jdbc.password</name>
        <value>oozie</value>
    </property>
  4. Copy the MySQL JDBC driver (mysql-connector-java-<version>-bin.jar) to the following directory:
    /opt/mapr/oozie/oozie-<oozieversion>/libext
  5. Execute the oozie-setup.sh script:
    /opt/mapr/oozie/oozie-<version>/bin/oozie-setup.sh -hadoop <version> /opt/mapr/hadoop/hadoop-<version>
  6. Start the Oozie server:
    maprcli node services -name oozie -action start -nodes <node-list>
  7. Check that MySQL is now in use by looking at the contents of the oozie.log file. For example:
    cat /opt/mapr/oozie/oozie-<version>/logs/oozie.log |grep mysql
