Sangjin Lee commented on YARN-4670:
-----------------------------------

volume of logging depends on the number of nodes which are free and and how
many are blacklisted for the application and how long other nodes are occupied.
but IMO it would be rare scenario volume explodes and we can have logging for
it in AppSchedulingInfo.isBlackListed , Thoughts ?

Yes that sounds like a plan.
> add logging when a node is AM-blacklisted
