{quote}
in this case, you assign the rc code to BookieHandleNotAvailableException. But it seems no so suitable, because actually the connect operation succeed and bookie is available. I think we need a better rc code here.
besides that, just be curious why you changed log level from DEBUG to INFO for connecting message.

It was a pretty long time. In fact, I forgot about it and came back several minutes later. It was there hung in that test. Now it is making progress just fine.

Ivan Kelly commented on BOOKKEEPER-485:
---------------------------------------
BookieHandleNotAvailableException is the closest to what has happened. The channel has been closed, so the bookie handle, is in fact not available. If clients need more details, they need to look at the logs. This isn't an error they should be able to recover from. If this occurs they need to fix their code.
It's useful to know which thread triggered the connect. The log on connection and disconnection are both INFO, so it made little sense to have this one as DEBUG, and it was annoying to have to enable debug logging just for this output.

Ivan Kelly commented on BOOKKEEPER-485:
---------------------------------------
Ok, so it's similar to BOOKKEEPER-5, but not the same. Basically, there's a race between closing the PerChannelBookieClient and the connection completing. If the PerChannelBookieClient requests to connect, and then is closed before the request completes, then the channel object returned on successful connection is orphaned. The fix is simple, im running in loop now. A succinct repo should be easy enough to implement as well.

Ivan Kelly updated BOOKKEEPER-485:
----------------------------------
Attachment: 0001-BOOKKEEPER-485-Fix-race-between-PerChannelBookieClie.patch
Fix is simple. Set the channel state to disconnected on close. If, on connection completion, the callback sees the state is in disconnected (rather than connecting), close the channel, and abort ops. The test case will successfully repro the issue if run without the fix, but the whole thing hangs due to releaseExternalResources being completely uninterruptible.

Flavio Junqueira commented on BOOKKEEPER-485:
---------------------------------------------
It looks good, just a couple of comments:
- I don't think this statement is needed: state = ConnectionState.DISCONNECTED;
- The test case is not really deterministic, although I understand that running it 1000 times will probably trigger it once. I can't come up with a good way of making it deterministic, though, so it is fine with me to have it like that. I just wanted to make the point and perhaps have a comment on the description of the test case for future reference.
- In ZooKeeper, we often have a {@link http://issues.apache.org/...} tag to link the test case to the jira issue. I like it, so I suggest we use it here too, but if you people don't like, we don't have to do it. Just a text reference as you have now is ok.
