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, is applied. To manually apply the latest changes, see 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 2.3 and Tez 0.9. For configuration information, see Configuring Hive 2.3 and Tez 0.9.
