Shuai Zhang commented on YARN-8467:
-----------------------------------
Because it's just related to debug logs, there's no need to add new unit tests.
> AsyncDispatcher should have a name & display it in logs to improve debug

> 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
