Socket is not connected
Hi, I managed to upgrade my zookeeper 2 application to zookeeper 3.1.1/ All my tests run though my logs is full of following exception. In my code I basically just invoice ZooKeeper.close(); Any idea what the problem could be?

Re: Socket is not connected
Hi Stefan, There's a timing issue when the client closes the connection. It sends a session close to the server and then starts to close it's own sockets. If the server closes the socket before the client does you can sometimes see the client get java.net.SocketException: Socket is not connected we are a bit paranoid about making sure you/we can debug unusual situations, so we include the trace in the WARN message in the log, just in case. In this situation though it is not an issue, in other situations (say the server drops it's connection) it would help to have the trace in a debugging situation, so we include it. Btw, in general in the code if we are more concerned about an event we would output as an ERROR, not as a WARN.

[ANNOUNCE] Apache ZooKeeper 3.1.1
The Apache ZooKeeper team is proud to announce Apache ZooKeeper version 3.1.1. ZooKeeper is a high-performance coordination service for distributed applications. It exposes common services - such as naming, configuration management, synchronization, and group services - in a simple interface so you don't have to write them from scratch. You can use it off-the-shelf to implement consensus, group management, leader election, and presence protocols. And you can build on it for your own, specific needs. If you are upgrading from version 2.2.1 on SourceForge be sure to review the 3.0.1 release notes for migration instructions. For ZooKeeper release details and downloads, visit: http://hadoop.apache.org/zookeeper/releases.html ZooKeeper 3.1.1 Release Notes are at: http://hadoop.apache.org/zookeeper/docs/r3.1.1/releasenotes.html Regards, The ZooKeeper Team
Re: Socket is not connected
Hi Patrick, thanks for the clarification. I can see your point but as user of zookeeper I personal would prefer to have this as debug message. Maybe something like log.debug(WARN: + msg). ... just a user feedback.

Re: Socket is not connected
Thanks for the feedback. It's definitely not a clearcut decision on how to log it. As most ppl tend to run in INFO level on production systems we wanted to keep it visible for the time being.
