Pre-Upgrade Steps for Pig

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

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

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