Subject [jira] [Commented] (YARN-4107) Both RM becomes Active if all zookeepers can not connect to active RM
Date Wed, 21 Oct 2015 21:29:27 GMT

    [ https://issues.apache.org/jira/browse/YARN-4107?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14967974#comment-14967974

Xuan Gong commented on YARN-4107:
---------------------------------

Offline discussed this with [~kasha]. The approach in attached patch is too aggressive. 

bq. If it fails to connect to ZK, the fencing thread should fail and lead to the RM switching
to standby state

Yes, it is.

To fix the described issue, tune the configuration might be a better solution for now.

Close this as invalid.
