win eclipse 提交job到hadoop集群报错

用eclipse插件在window编写mapreduce程序，设置
conf.set("fs.defaultFS.name", "192.168.215.142:8020");
conf.set("mapreduce.framework.name", "yarn");
conf.set("yarn.resourcemanager.address", "192.168.215.142:8032");

提交到hadoop，为什么如下错误
Exception in thread "main" java.io.IOException: The ownership on the staging directory /tmp/hadoop-yarn/staging/LT/.staging is not as expected. It is owned by Administrators. The directory must be owned by the submitter LT or by LT

window的用户为LT，hadoop上的用户为hadoop

本地hadoop版本与集群hadoop版本，还有配置文件是否一致

解决办法：
1、如果是测试环境，可以取消hadoop hdfs的用户权限检查。打开conf/hdfs-site.xml，找到dfs.permissions属性修改为false（默认为true）OK了。 ，
