Varun Saxena commented on YARN-6156:
------------------------------------

bq. I agree that non-exclusive nodes are bounded by available resources. 
However if some resource are obtained from any such node, we have to increase 
and update nodes count to SimpleBlacklistManager and then decrease node count 
when resources are removed
Agree in principle.

> As per the current implementation for AM blacklisting disabling is based on 
> completed custer resource.
> Incase of partitioned cluster, nodes applicable for AM labels only should be 
> considered as total nodes.
