Zhijie Shen updated YARN-2565:
    Attachment: YARN-2565.1.patch

Create a patch to make the configurations for ApplicationHistoryServer using 
old storage stack and enabling RMApplicationHistoryWriter at RM side 
consistent. And only when FileSystemApplicationHistoryStore is explicitly set, 
we're going to use the new stack.

> RM shouldn't use the old RMApplicationHistoryWriter unless explicitly setting 
> FileSystemApplicationHistoryStore
