------------------------------------------
Summary: Handle unknown error for rolling upgrade old client new
server scenario
Key: ZOOKEEPER-2695
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2695
Project: ZooKeeper
Issue Type: Bug
Components: java client
Reporter: Mohammad Arshad
In Zookeeper rolling upgrade scenario where server is new but client is old,
when sever sends error code which is not understood by the client, client
throws IllegalArgumentException. Generally IllegalArgumentException is not
handled by any of the ZK applications.
KeeperException.SystemErrorException should be thrown instead of
IllegalArgumentException
