Junping Du commented on YARN-3046:
----------------------------------
bq. If that turns out to be the case, we could conceivably create subclasses in
a standard place for MR, and have all use cases use those concrete subclasses.
But I'm fine deferring that aspect a little bit. It's not a critical point.
Another option is to make HierarchicalTimelineEntity non abstract? I also agree
we should open a new JIRA to discuss this later.
