Subject [jira] [Commented] (YARN-3705) forcemanual transition of RM active/standby state in automatic-failover mode should change elector state
Date Sat, 23 May 2015 01:00:19 GMT

    [ https://issues.apache.org/jira/browse/YARN-3705?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14557067#comment-14557067
] 

Masatake Iwasaki commented on YARN-3705:
----------------------------------------

Thanks for the comment, [~kasha]. I expected that ZKFailoverController (running as external
process of NameNode) detects the status change of NameNode and quitElection in HDFS case..
I will check the behaviour in HDFS again.

> Executing {{rmadmin -transitionToActive --forcemanual}} and {{rmadmin -transitionToActive
--forcemanual}} in automatic-failover.enabled mode changes the active/standby state of ResouceManager
while keeping the state of ActiveStandbyElector. It should make elector to quit and rejoin
otherwise forcemanual transition should not be allowed in automatic-failover mode in order
to avoid confusion.
