　　　参考文献：https://issues.apache.org/jira/browse/HADOOP-8089

　　　错误信息如下：

　　　　ERROR security.UserGroupInformation: PriviledgedActionException as: hadoop cause:java.io.IOException Failed to set permissions of path:\usr\hadoop\tmp\mapred\staging\hadoop753422487\.staging to 0700 Exception in thread "main" java.io.IOException: Failed to set permissions of path: \usr\hadoop\tmp \mapred\staging\hadoop753422487\.staging to 0700

　　　解决方法：

Configuration conf = new Configuration();

conf.set("mapred.job.tracker", "[server]:9001");

　　 "[server]:9001"中的"[server]"为Hadoop集群Master的IP地址。
