Karthik Kambatla updated YARN-6246:
-----------------------------------
Description: Currently, the starvation checks are done holding the
scheduler writelock. We are probably better of doing this outside. (was:
Given the update thread holds the scheduler write-lock, we are probably better
of computing starvation and identification of starved apps in a different
thread.
I am averse to adding a thread that runs on a *configurable timeout*, but maybe
we could trigger this thread after every update run, or do this in the update
thread but outside of the write-lock. )
