Feng Yuan commented on YARN-7108:
---------------------------------
Agree with [~bibinchundatt], pre job ResourceRequest label is setted when
submitted(as when as before you modify xml file).
And these requests have been stored in rm, could not be change.
But the new job get the new label is reasonable.
