Zhijie Shen updated YARN-1749:
------------------------------
Attachment: YARN-1749.1.patch
Create a patch, which is on top of YARN-1732 and YARN-1687. It fixes the old
AHS configurations, in order not to confuse people who only want to use
timeline service to record per-framework data. And timeline is used as the
prefix term for all the ahs configurations after change, because generic
history can be considered as the specific part of timeline service.
In addition, I uniformed the the store class for AHS and RM. It doesn't make
sense the two store are different.

> We need to:
> 1. Review the configuration names and default values
> 2. Combine the two store class configurations
> Some other thoughts:
> 1. Maybe we don't need null implementation of ApplicationHistoryStore any more
> 2. Maybe if yarn.ahs.enabled = false, we should stop AHS web server returning
> historic information
