[jira] [Commented] (YARN-953) [YARN-321] Change ResourceManager to use HistoryStorage to log history data

    [ 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?
