Jason Gustafson resolved KAFKA-8242.
------------------------------------
Resolution: Fixed
Marking this as resolved. We believe we having fixed the cause of the
coordinator fenced error and we have also improved the replica fetcher behavior
in KIP-461, as Dhruvil notes.

> That a single corrupt partition can affect the availability of multiple
> topics is a great concern to us.
