> Since we have "yarn cluster -lnl" to print all nodelabels info .But it's not
> enough,we should be abale to list nodes collection partitioned by
> labels,especially in large cluster.
> So I propose to add an optional argument "-nodes" for "yarn cluster -lnl"
> to achieve this.
> e.g.
> [yarn@docker1 ~]$ yarn cluster -lnl -nodes
> Node Labels Num: 3
> Labels Nodes
> <tensorflow:exclusivity=true> docker1:45454, docker5:45454
> <spark:exclusivity=true> docker2:45454
> <impala:exclusivity=true> docker3:45454
