>  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
> YARN-8467 introduce another parameter to name AsyncDispatcher. This is an 
> alternative to just use the thread name as AsyncDispatcher name.
