[jira] [Commented] (YARN-3705) forcemanual transition of RM active/standby state in automatic-failover mode should change elector state

["Karthik Kambatla (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/YARN-3705?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14556946#comment-14556946 ] 

Karthik Kambatla commented on YARN-3705:
----------------------------------------

Yarn follows HDFS behavior here. Force-manual is discouraged and messes with automatic failover. I understand the proposed improvement would help with this, but would like to make sure the behavior is consistent across HDFS and Yarn.

> 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.
