Tsuyoshi OZAWA commented on YARN-1701:
--------------------------------------

Updated a patch based on Zhijie's idea. It looks reasonable to me.

[~jira.shegalov] sorry for cutting in. I updated a patch because this issue is blocker of
2.4.1 release. Please feel free to take it back to you.

> When I enable AHS via yarn.ahs.enabled, the app history is still not visible in AHS webUI.
This is due to NullApplicationHistoryStore as yarn.resourcemanager.history-writer.class. It
would be good to have just one key to enable basic functionality.
> yarn.ahs.fs-history-store.uri uses {code}${hadoop.log.dir}{code}, which is local file
system location. However, FileSystemApplicationHistoryStore uses DFS by default.
