this method may be invoked by life cycle operations which need to tear down the bigdata environment . normally you do not need to do this as the cleaner service uses a daemon thread and will not prevent the jvm from halting . however , a servlet container running bigdata can complain that some threads were not terminated if the webapp running bigdata is stopped . you can invoke this method to terminate the stale reference cleaner thread .
