换成hdfs执行命令即可:sudo -u hdfs hadoop fs -ls /user
[root@vmocdp125 conf]# sudo -u hdfs hadoop fs -ls /userFound 6 itemsdrwxrwx--- - ambari-qa hdfs 0 2016-09-14 19:48 /user/ambari-qadrwxr-xr-x - hcat hdfs 0 2016-09-14 20:09 /user/hcatdrwx------ - hdfs hdfs 0 2016-09-20 18:51 /user/hdfsdrwxr-xr-x - hive hdfs 0 2016-09-14 20:11 /user/hivedrwxr-xr-x - hdfs hdfs 0 2016-09-20 18:49 /user/ocetldrwxrwxr-x - spark hdfs 0 2016-09-14 20:00 /user/spark
