Pre-Upgrade Steps for Oozie

Complete the following steps before you upgrade Oozie with or without the MapR Installer.

  1. Stop any jobs or coordinators that are in a RUNNING or SUSPENDED state.
  2. For upgrades without the MapR Installer: Stop the Oozie service.
    # sudo -u mapr maprcli node services -name oozie -action stop -nodes <node names>
  3. Back up Oozie configuration files and save them to a location outside the MapR installation. Configuration properties are located in /opt/mapr/oozie/oozie-<version>/conf/. After upgrading, you can reapply changes to the updated Oozie installation using the backup.
  4. For upgrades without the MapR Installer: Remove the old share libraries and examples from the following directories:
    maprfs:///oozie/share
    maprfs:///user/${user.name}/examples
