Steve Loughran commented on YARN-4695:
--------------------------------------
..hostname of www.bbc.co.uk/0.0.0.0:8032. is just 127.0.0.1 with the usual set
of domains disabled. And as usual, IPC client doesn't detect "0.0.0.0" as an
invalid IP address. Even if IPC client does (it should), ATS can and fail fast
> EntityGroupFSTimelineStore to not log errors during shutdown

> # The {{EntityGroupFSTimelineStore}} threads log exceptions that get raised
> during their execution.
> # the service stops by interrupting all its workers
> # as a result, the workers all log exceptions at error *even during a managed
> shutdown*
> # this creates distracting noise in logs
