> The methods closeSession of 
> org.apache.hive.service.cli.session.SessionManager use 
> synchronized for thread safe, i looked at the code and wonder why there's need for synchronized.
> Because closeSession sometimes use the hadoop ipc call and takes too much time to response, so if it is possible to remove the keyword synchronized.
