Li Lu commented on YARN-4265:
-----------------------------

Sorry by saying YARN-4234 I'm actually meaning YARN-3942.

> To support the newly proposed APIs in YARN-4234, we need to create a new plugin timeline
store. The store may have similar behavior as the EntityFileTimelineStore proposed in YARN-3942,
but cache date in cache id granularity, instead of application id granularity. Let's have
this storage as a standalone one, instead of updating EntityFileTimelineStore, to keep the
existing store (EntityFileTimelineStore) stable.
