---------------------------------

             Summary: AsyncDispatcher should have a name & display it in logs to improve debug
                 Key: YARN-8467
                 URL: https://issues.apache.org/jira/browse/YARN-8467
             Project: Hadoop YARN
          Issue Type: Improvement
    Affects Versions: 3.1.0
            Reporter: Shuai Zhang


Currently each AbstractService has a dispatcher, but the dispatcher is not named. Logs from dispatcher is mixed, which is quite hard to debug any hang issues. I suggest
 # Make it possible to name AsyncDispatcher & its thread (partially done in YARN-6015)
 # Mention the AsyncDispatcher name in all its logs
