> In SessionState class, currently we will always try to get a HMS connection in {{start(SessionState
startSs, boolean isAsync, LogHelper console)}} regardless of if the connection will be used
later or not. 
> When SessionState is accessed by the tasks in TaskRunner.java, although most of the tasks
other than some like StatsTask, don't need to access HMS. Currently a new HMS connection will
be established for each Task thread. If HiveServer2 is configured to run in parallel and the
query involves many tasks, then the connections are created but unused.
