Description

Find one case when run ITBLL. And the regionserver hang when abort as need to waitAllRegionClose. But System.exit need to run shutdown hook. And the hook can't finished as the RS thread is still alive. So use Runtime.getRuntime().halt to terminate regionserver and this method will not run any shutdown hook.
