Varun Saxena commented on YARN-5792:
------------------------------------
bq. If we can guarantee the created time is made always available for all kinds
of update scenarios, then I'm fine with using the created time. What do you
think?
It should be available. For YARN container in NM it wasnt available across
restarts so I saved it in state store. For distributed shell, its not required.
For MR entities, there are certain events which seem to be only used by rumen
hence haven't handled them. Not sure why rumen has them though.
> adopt the id prefix for YARN, MR, and DS entities

> We introduced the entity id prefix to support flexible entity sorting
> (YARN-5715). We should adopt the id prefix for YARN entities, MR entities,
> and DS entities to take advantage of the id prefix.
