Junping Du commented on YARN-4265:
----------------------------------
I just commit YARN-4234. [~gtCarrera9], would you rebase your patch on latest
trunk branch? Thanks!
Hi [~jlowe], I saw your comments above: "This looks like most of the patch is a
copy of the entity timeline store from YARN-3942 with a few edits, so I'm sorta
reviewing my own code here. As such I did a diff of the patch from this JIRA
and the one from YARN-3942 so I could focus on what's changed. I'll defer to
others to review the parts that are identical to YARN-3942. Eventually I can
see this being a superset of YARN-3942, since it can cache to memory and either
cache everything or a subset based on what the plugins decide." Are you OK with
continue the review effort going with this patch? Or you have some other
preferences?

> 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.
