Clients get SESSION MOVED exception when switching from follower to a leader.
-----------------------------------------------------------------------------
Key: ZOOKEEPER-484
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-484
Project: Zookeeper
Issue Type: Bug
Affects Versions: 3.2.0
Reporter: Mahadev konar
Assignee: Mahadev konar
Priority: Blocker
Fix For: 3.2.1
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.
