If enterprise user and group information needs to be synchronized with Ranger, the Apache Ranger UserSync component must be installed in RANGER_USERSYNC_HOST:
Shut down your current Ranger usersync process, switch to the new version, and start Ranger UserSync:
service ranger-usersync stophdp-select set ranger-usersync 2.2.8.0-3150service ranger-usersync startTo validate the upgrade, go to /var/log/ranger/usersync and check for errors in the following files:
usersync.logauth.log
If the upgrade process fails, follow the steps in Downgrading the Cluster, starting with "Downgrade Ranger."
