Subject [jira] [Created] (YARN-2019) Retrospect on decision of making RM crashed if any exception throw in ZKRMStateStore
Date Sat, 03 May 2014 00:13:14 GMT
Junping Du created YARN-2019:
--------------------------------

             Summary: Retrospect on decision of making RM crashed if any exception throw in
ZKRMStateStore
                 Key: YARN-2019
                 URL: https://issues.apache.org/jira/browse/YARN-2019
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Junping Du
            Priority: Critical


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.
