Hi folks, We just discovered a bug in 3.2 release http://issues.apache.org/jira/browse/ZOOKEEPER-484.
This bug will affect your clients whenever they switch zookeeper servers - from a zookeeper server that is a follower to a server that is leader. We should have a fix out by next week in 3.2.1 and trunk. 3.2.1 should be out in the next 2-3 weeks. If you are already using 3.2.0 in production I would suggest switching it back to 3.1.1 (though there is a workaround mentioned in the jira http://issues.apache.org/jira/browse/ZOOKEEPER-484 but I would advise against it). The 3.2.0 clients are compatible with 3.1.1 servers. Thanks mahadev
