Varun Saxena commented on YARN-6148:
------------------------------------
bq. IIUC we don't track label of nodes in AM side of MR
We get map and reduce labels from MR configurations
mapreduce.map.node-label-expression and mapreduce.reduce.node-label-expression
respectively if this is what you were asking.
For using the count per label, a sibling Mapreduce JIRA will have to be opened.
Will do so after making some progress on this JIRA.
> NM node count reported to AM in Allocate Response should consider requested
> node label partitions.
