Subject [jira] [Commented] (YARN-5792) adopt the id prefix for YARN, MR, and DS entities

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.

> 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.
