Subject [jira] [Commented] (YARN-5685) Non-embedded HA failover is broken
Date Wed, 28 Sep 2016 21:41:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-5685?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15530963#comment-15530963
] 

Daniel Templeton commented on YARN-5685:
----------------------------------------

BTW, the bug introduced by YARN-4559 (that I had in the original description) would break
non-embedded failover if it worked, but since it doesn't, it's kinda harmless.  Still wrong,
though.

> If HA is enabled with automatic failover enabled and embedded failover disabled, all
RMs all come up in standby state.  To make one of them active, the {{--forcemanual}} flag
must be used when manually triggering the state change.  Should the active go down, the standby
will not become active and must be manually transitioned with the {{--forcemanual}} flag.
