Subject [jira] [Commented] (YARN-5685) Non-embedded HA failover is broken
Date Fri, 24 Mar 2017 20:59:41 GMT

    [ https://issues.apache.org/jira/browse/YARN-5685?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15941122#comment-15941122

Karthik Kambatla commented on YARN-5685:

Have no recollection from my previous review. Looked through again. Minor comments:
# In the javadoc for {{verifyLeaderElection}}, the @link annotation is missing the closing
# In TestRMAdminService, can we split the three cases in the test to three individual tests.

> 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.
