> Sometimes, event-group thread of netty’s is not stopped. because jvm will
> start a shutdown-hook after all thread is stopped without kill signal. it is
> dead-lock state.
> We should explicitly call to shutdown the event-group thread of netty’s and
> should set a shutdown-hook order
> For example, before you start up TajoMaster, runs tsql, you can find deadlock
