Wangda Tan commented on MAPREDUCE-6304:
---------------------------------------
[~Naganarasimha],
Actually now CS will check label-expression of ANY resource request matches
labels on nodes before allocating rack/node local requests. IAW,
node-label-expression of rack/node local request will be ignored and will be
treated as same as ANY request. To reply your concern:
MR tasks run only on the labeled nodes.
Since this changes MR configuration, I will wait for another couple of days
before commit this.
Thanks,
