Subject [jira] [Commented] (YARN-1861) Both RM stuck in standby mode when automatic failover is enabled
Date Mon, 12 May 2014 22:40:16 GMT

    [ https://issues.apache.org/jira/browse/YARN-1861?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13995743#comment-13995743
] 

Karthik Kambatla commented on YARN-1861:
----------------------------------------

bq. Also, we need to make sure that when automatic failover is enabled, all external interventions
like a fence like this bug (and forced-manual failover from CLI?) do a similar reset into
the leader election. There may not be cases like this today though.
One way to future-proof this is to call resetLeaderElection in ResourceManager#transitionToStandby
itself. That looks hacky, but doesn't require new external interventions to explicitly handle
it. [~vinodkv] - do you think that would be a better approach?

> In our HA tests we noticed that the tests got stuck because both RM's got into standby
state and no one became active.
