Li Lu updated YARN-4219:
------------------------
Attachment: YARN-4219-trunk.001.patch
Upload a patch to add the leveldb cache storage. To organize this storage, I
refactored MemoryTimelineStore, moved the abstract logic to operate on a
general map of entities into a new MapTimelineStore. Both MemoryTimelineStore
and LevelDbCacheTimelineStore are MapTimelineStores, communicating through the
abstract logic through a TimelineStoreMapAdapter.
> New levelDB cache storage for timeline v1.5

> 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.
