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

Do we have an explicit check for not sharing for AM containers? This point did 
come up when we were discussing offline but we were under the impression its 
not enforced.
Either ways, it does not make much sense to launch AM container on a shared 
label though.

> 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.
