Weiwei Yang commented on YARN-1013:
-----------------------------------
Hi [~haibochen], [~elgoiri]
I took a look at YARN-1015, it is a similar implementation like what we've done
internally.
However one thing to double check, what was the conclusion of the discussion
the other day between you, [~leftnoteasy] and [[email protected]] ?
Since YARN-8178 was proposed but a different approach. Do we need to get this
one done too and expose both 2 approaches to users? Please let me know, thanks.
