> In previous implementation for HADOOP-8468, 3rd replica is avoid to place on
> the same nodegroup of 2nd replica. But it didn't provide check on nodegroup
> of 1st replica, so if 2nd replica's rack is not efficient to place replica,
> then it is possible to place 3rd and 1st replica within the same node group.
> We need a change to remove all nodes from available nodes for placing replica
> if there already replica on the same nodegroup.
