      Description

      signalToContainer REST API introduced in YARN-8693 does not work even if requested by the app owner.
      It works well only if requested by an admin user

      $ kinit kwnam
      Password for kwnam@TEST.ORG:
      $ curl  -H 'Content-Type: application/json' --negotiate -u : -X POST https://rm002.test.org:8088/ws/v1/cluster/containers/container_e58_1573625560605_29927_01_000001/signal/GRACEFUL_SHUTDOWN
      {"RemoteException":{"exception":"ForbiddenException","message":"java.lang.Exception: Only admins can carry out this operation.","javaClassName":"org.apache.hadoop.yarn.webapp.ForbiddenException"}}$
      $ kinit admin

      $ curl  -H 'Content-Type: application/json' --negotiate -u : -X POST https://rm002.test.org:8088/ws/v1/cluster/containers/container_e58_1573625560605_29927_01_000001/signal/GRACEFUL_SHUTDOWN
      $
      

      in contrast, the app owner can do it using the command line as below.

      $ kinit kwnam
      Password for kwnam@TEST.ORG:
      $ yarn container -signal container_e58_1573625560605_29927_01_000002  GRACEFUL_SHUTDOWN
