Zhijie Shen updated YARN-2033:
------------------------------

    Attachment: YARN-2033.5.patch

Rebase the patch according to the latest trunk, make 
AppicationHistoryManagerOnTimelineStore throw XXXXNotFoundException instead of 
returning null, to be consistent with the existing behavior. The patch also 
includes some minor improvement.

> Investigate merging generic-history into the Timeline Store

> Having two different stores isn't amicable to generic insights on what's 
> happening with applications. This is to investigate porting generic-history 
> into the Timeline Store.
> One goal is to try and retain most of the client side interfaces as close to 
> what we have today.
