[jira] [Created] (YARN-8693) Add signalToContainer REST API for RMWebServices

Tao Yang created YARN-8693:
------------------------------

             Summary: Add signalToContainer REST API for RMWebServices
                 Key: YARN-8693
                 URL: https://issues.apache.org/jira/browse/YARN-8693
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: restapi
    Affects Versions: 3.2.0
            Reporter: Tao Yang
            Assignee: Tao Yang


Currently YARN has a RPC command which is "yarn container -signal <container ID [signal command]>" to signal OUTPUT_THREAD_DUMP/GRACEFUL_SHUTDOWN/FORCEFUL_SHUTDOWN commands to container. That is not enough and we need to add signalToContainer REST API for better management from cluster administrators or management system.
