Naganarasimha G R commented on MAPREDUCE-6304:
----------------------------------------------
Thanks for detailed clarification, got what you intended and was planning to do
the same way, i.e. only if "mapreduce.job.map.node-label-expression" or
"mapreduce.job.reduce.node-label-expression" config are set then modify the ask
in {{RMContainerRequestor}} as yarn takes care of setting in
{{ApplicationMasterService}} when no labels specified in resource request for
mapper and reducer and in {{RMAppManager}} for AM.
