----------------------------------
Hi [~vrushalic], thanks for updating the patch. A quick question here:
Looks like we only specify three tracks for entity: FLOW, USER and QUEUE
{code}
+public enum AggregateUpTo {
+ FLOW,
+ USER,
+ QUEUE
+}
{code}
But we have more tracks (type) in YARN-3041.
{code}
+public enum TimelineEntityType {
+ YARN_CLUSTER,
+ YARN_FLOW,
+ YARN_APPLICATION,
+ YARN_APPLICATION_ATTEMPT,
+ YARN_CONTAINER,
+ YARN_USER,
+ YARN_QUEUE;
{code}
May be we should add more here?

> Per design in YARN-2928, come up with the interface for the ATS writer to
> write to various backing storages. The interface should be created to capture
> the right level of abstractions so that it will enable all backing storage
> implementations to implement it efficiently.
