> Now TimelineWebServices contains non-trivial logic to process the HTTP requests, manipulate
the data, check the access, and interact with the timeline store.
> I propose the move the data-oriented logic to a middle layer (so called TimelineDataManager),
and TimelineWebServices only processes the requests, and call TimelineDataManager to complete
the remaining tasks.
> By doing this, we make the generic history module reuse TimelineDataManager internally
(YARN-2033), invoking the putting/getting methods directly. Otherwise, we have to send the
HTTP requests to TimelineWebServices to query the generic history data, which is not an efficient
way.
