The title of the exception is "java.util.concurrent.TimeoutException: Timed out(5000) waiting for operation"! How can I set a approprate time for not exceeding the time out limit?! The whole exeption stack is:
**java.util.concurrent.TimeoutException: Timed out waiting for operation

A lot of reason can cause the ttserver client throw TimeoutException. In my situation, it was because of the replication to a node which did not exist.So when delete the startup parameters mhost and mport,the problem was fixed.....
Hope this can help someone else....
