有时候上述这样kill做下来，并不管用，得再来

同时，大家要注意，是否是进程的消失？
也会是你的slave1 还是 slave2的进程自动消失了。注意 ，这是个很隐蔽的问题。
重新停止集群，再重新启动集群。
如果还是出现这个问题的话，则
关于这里参数配置的解释，见
Hadoop YARN配置参数剖析(2)—权限与日志聚集相关参数
注意，对master、slave1和slave2都要操作，然后，再[hadoop@master hadoop-2.6.0]$ sbin/stop-all.sh
再[hadoop@master hadoop-2.6.0]$ sbin/start-all.sh即可。
成功！
