[jira] [Commented] (AMBARI-25956) [ Rolling upgrade] Hive Server Going down after upgrade
[ https://issues.apache.org/jira/browse/AMBARI-25956?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17736192#comment-17736192 ]
D M Murali Krishna Reddy commented on AMBARI-25956:
---------------------------------------------------
I too have observed this behaviour during rolling, express upgrades. Once the upgrade is completed I can see only one hiveserver2 running.
On Checking the upgrade logs I can see that during restarting HiveServer2, deregister is being executed with the target version of upgrade. Due to this the HiveServer2 which restarts currently is stopping the HiveServer's that have restarted earlier.
I feel the change done in hive_server_upgrade.py from https://issues.apache.org/jira/browse/AMBARI-21722 has induced this issue of deregistering target version instead of source version. As, In few earlier tickets AMBARI-12195 , AMBARI-12280 It's mentioned that expected behaviour is deregistering source version.
