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:
  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 the Oozie Server to use SSL
    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.
