-----------------------------------------
Attachment: MAPREDUCE-6304.20150501-1.patch
Hi [~wangda], have incorporated changes for {{add mapper/reducer
node-label-expression}} also incorported limitations set by YARN-2694(Ensure
only single node label specified in ResourceRequest) which limits labels to be
supported on only "ANY" ResourceRequests.
But one query what i have is : Isnt it a serious limitation if labels are
supported for only ANY resource requests?
