Summary: Add an optional arg to yarn cluster -list-node-labels to list all nodes collection partitioned by labels
Key: YARN-7975
URL: https://issues.apache.org/jira/browse/YARN-7975
Project: Hadoop YARN
Issue Type: Improvement
Reporter: Shen Yinjie
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
