URL: https://issues.apache.org/jira/browse/AMBARI-8593
Project: Ambari
Issue Type: Technical task
Components: ambari-server
Affects Versions: 2.0.0
Reporter: Alejandro Fernandez
Assignee: Alejandro Fernandez
Fix For: 2.0.0
Services will need a pre-restart and post-restart hook that can perform the
following actions.
Pre-restart, needs to call hdp-select with the version number. It should only
be called during a RESTART command that is performed during a Rolling Upgrade.
Post-restart, needs to perform several checks, like ZK quorum is established
and namenode is live.
