---------------------------------
For Nicholas:
I have runned all the unit tests and triggered two issue: MAPREDUCE-4906 and
MAPREDUCE-4904
These two issue can be reproduce without this patch HDFS-4337
I will resolve them
Thank you
> Backport HDFS-4240 to branch-1: Make sure nodes are avoided to place replica
> if some replica are already under the same nodegroup.
