Hi， My hadoop cluster has been running for a period of time. Now i want to close it for some system changes. But the command "bin/stop-all.sh" shows "no jobtracker to stop","no tasktracker to stop","no namenode to stop" and "no datanode to stop". I use "jps" got nothing but jps itself. However, hadoop is indeed running.I think it may be some tmp files about hadoop had been cleared by operation system. Could someone tell me how to stop hadoop in case of no data files breaks ? Any guidance would be greatly appreciated. Thanks!
