-----------------------------
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.
