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.
    # mapr maprcli node services -name oozie -action stop -nodes <node names>
  3. (OPTIONAL) 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
  5. For upgrades from MEP 3.0.x to MEP 4.0 (or later): If you are upgrading Oozie 4.3.0 on a secure cluster and you have not already configured SSL on your Oozie server and client, you must perform the following steps:
    1. Configuring Oozie on a Secure Cluster
    2. Configuring Oozie Clients to Use SSL (Oozie 4.3.0)

Preserving Oozie Configuration

Starting from 1808 release, MEP 4.1.2, MEP 5.0.1, MEP 6.0.0 and newer versions, in case of a version update, configuration from a previously installed version of Oozie is stored in a folder with an old version timestamp.
