list hdfs directories

dfs.data.dir is set to /u01/hadoop/dfs ..../u12/hadoop/dfs

 

I am assuming /u01/hadoop/dfs ..../u12/hadoop/dfs are hdfs filesystems.

 

When i query to list hdfs filesystems, i get the error...what am i missing and how can i list the hdfs directories under /u01../u12

 

[root@bda1node02 ~]#  hdfs dfs -ls /u01
ls: `/u01': No such file or directory
[root@bda1node02 ~]#

 

 

 

Thanks

Re: list hdfs directories

dfs.data.dir refers to directories on the datanode's local filesystem that
store HDFS blocks. The command "hdfs dfs" talks to the Namenode to query
HDFS for a directory /u01. These won't match up (even if identical
directory names do exist).

You can begin by running "hadoop fs -ls /" to get a listing of all top
level directories on HDFS
