Description

Steps:

1) Install Hadoop 3.0 cluster
2) Run Yarn service application

sleeper.json

{
  "name": "sleeper-service",
  "components" : 
    [
      {
        "name": "sleeper",
        "number_of_containers": 1,
        "launch_command": "sleep 900000",
        "resource": {
          "cpus": 1, 
          "memory": "256"
       }
      }
    ]
}

cmd

yarn app -launch my-sleeper1 sleeper.json

3) stop yarn service app

cmd

yarn app -stop my-sleeper1

On stopping yarn service, appId finishes with YarnApplicationState: FINISHED , FinalStatus Reported by AM: ENDED and Diagnostics: Navigate to the failed component for more details.

Here, Diagnostics message should be improved. When an application is explicitly stopped by user, the diagnostics message should say " Application stopped by user"
