Li Lu updated YARN-4219:
------------------------
Attachment: YARN-4219-YARN-4265.001.patch
I rebased my YARN-4219 patch on top of YARN-4265 since the caching storage is
an extension on the main plugin storage. I also changed some class names to
better reflect their implementations. The current patch applies on top of
YARN-4265, which on top of YARN-4234.

> We need to have an "offline" caching storage for timeline server v1.5 after
> the changes in YARN-3942. The in memory timeline storage may run into OOM
> issues when used as a cache storage for entity file timeline storage. We can
> refactor the code and have a level db based caching storage for this use
> case.
