--------------------------------
Summary: Create yarn node-labels CLI to enable list node labels
collection and node labels mapping
Key: YARN-2786
URL: https://issues.apache.org/jira/browse/YARN-2786
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Wangda Tan
Assignee: Wangda Tan
With YARN-2778, we can list node labels on existing RM nodes. But it is not
enough, we should be able to:
1) list node labels collection
2) list node-to-label mappings even if the node hasn't registered to RM.
The command should start with "yarn node-labels ..."
