It is easy to reproduce. For example IOException will be thrown from
BucketWriter after all DataNodes in cluster become unavailable. I believe
that in that case, BucketWriter won't return to operational state even if
cluster is back and ready to use. It is probably a good idea to discard
BucketWriters after IOException. Do you agree?
I've filed a jira with stack trace in attached file:
