Post-Upgrade Steps for Tez

Complete the following steps after you upgrade Tez with or without the MapR Installer.

After a minor version update, for example from Tez-0.9-1808 to Tez-0.9-1901, no changes to the user configuration, tez-site.xml file, are applied. To apply the latest changes manually, see the Tez Release Notes.
  1. (Optional) Migrate any custom configuration settings into the new default files in the /opt/mapr/tez/tez-<old version>/conf/ directory.
  2. If you are using the MapR Installer, no additional steps are required. For manual installation, you need to configure Hive and Tez. See Configuring Hive and Tez.
