----------------------------------------------
Hi [~wangda]
One suggestion for this patch : labels will be applicable for only for {{Any}}
resource requests, so would it be better to have a config, based on which rack
local and node specific will not be submitted and only {{Any}} resource
requests with label will be submitted ? This will ensure that MR tasks run only
on the labelled nodes.
If the existing support to labels are sufficient then can we push this in ?

> Per the discussion on YARN-796, we need a mechanism in MAPREDUCE to specify
