Subject [jira] [Commented] (YARN-953) [YARN-321] Change ResourceManager to use HistoryStorage to log history data
Date Thu, 01 Aug 2013 21:09:49 GMT

    [ https://issues.apache.org/jira/browse/YARN-953?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13726898#comment-13726898
] 

Zhijie Shen commented on YARN-953:
----------------------------------

bq. Instead of adding a new DummyApplicationHistoryWriter, we can just use the InMemoryStorage
that is being worked on the other JIRA. The default should be InMemoryStorage. Can you work
on top of YARN-956?

DummyApplicationHistoryWriter is used to disable application history service, as RMStateStore
uses NullRMStateStore to disable RM recovery. Otherwise,  we need to check whether the writer
is enabled everywhere writer is called. Thoughts?
