Robert Kanter commented on YARN-3041:
-------------------------------------
{quote}the relates/is related entities and parent/children entities become IDs,
we can not simply do the check. Caller needs to make sure the relationship be
properly set. At the server side, we need to do the check too. Thoughts?{quote}
That's true. Otherwise, we'd have to go look them up somehow. I think it's
fine to have the caller/server ensure this is correct. We can always revisit
this later as well if it becomes a problem.
