Pre-Upgrade Steps for Mahout

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

You need to back up configuration files if you made configuration changes that you want to carry over to the next version.

To back up configuration files:

  1. Locate configuration files in /opt/mapr/mahout/mahout-<version>/conf/ directory.
  2. Copy the files to a location outside the MapR installation.
    After upgrading, you can reapply changes to the updated Mahout installation using the backup.
