> 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
