stack commented on HBASE-20507:
-------------------------------

So, IIUC, this is different to what I see over in HBASE-20503 where I am 
writing a WAL and then it breaks ("Stream already broken"). In this case we 
roll the WAL and try to recover the file we had been writing too -- the one 
that was reporting "stream already broken" -- in the stream's recoverAndClose. 
Do we need to recover the lease in recoverAndClose?

On this patch, LGTM. Nice test. On the javac warning, I don't know how to 
avoid. Perhaps someone else does. Meantime push it I'd say.

> I tried locally with a UT, if we overwrite a file which is currently being 
> written, the old file will be completed and then deleted. If you call close 
> on the previous file, a no lease exception will be thrown which means that 
> the file has already been completed.
> So we do not need to close a file if it will be overwritten immediately, 
> since recoverLease may take a very long time...
