> Project: Zookeeper
> Issue Type: Bug
> Components: server
> Affects Versions: 3.2.0
> Reporter: Mahadev konar
> Assignee: Mahadev konar
> Priority: Blocker
> Fix For: 3.2.1, 3.3.0

>
> When a client is connected to follower and get disconnected and connects to a
> leader it gets SESSION MOVED excpetion. This is beacuse of a bug in the new
> feature of ZOOKEEPER-417 that we added in 3.2. All the releases before 3.2 DO
> NOT have this problem. The fix is to make sure the ownership of a connection
> gets changed when a session moves from follower to the leader. The workaround
> to it in 3.2.0 would be to swithc off connection from clients to the leader.
> take a look at *leaderServers* java property in
> http://hadoop.apache.org/zookeeper/docs/r3.2.0/zookeeperAdmin.html.
