Subject [jira] [Commented] (YARN-2019) Retrospect on decision of making RM crashed if any exception throw in ZKRMStateStore
Date Sun, 04 May 2014 17:40:15 GMT

    [ https://issues.apache.org/jira/browse/YARN-2019?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13989059#comment-13989059

Bikas Saha commented on YARN-2019:
----------------------------------

That was the initial code since there was no HA states then. With HA states, the RM should
move into standby state upon store error.

> Currently, if any abnormal happens in ZKRMStateStore, it will throw a fetal exception
to crash RM down. As shown in YARN-1924, it could due to RM HA internal bug itself, but not
fatal exception. We should retrospect some decision here as HA feature is designed to protect
key component but not disturb it.
