Description:
when submit a sql to hiveserver, if the sql query timeout before compile, it
will continue compile and execute addShutdownHook, but now no thread to call
the close method of driver, so it alway stay in ShutdownHookManager's hooks,
causing a memory leak

the cancel from SQLOperation will set it's driver = null, so it can not call
the close method of driver
