Hi all,

I am running hadoop-0.20.2 on single node cluster,

I run the command

hadoop fsck /

it shows error:

Please suggest why it so..  it should show the health status:
     

Could you please review your configuration to see if you are pointing to
the right namenode address ? (This will be in core-site.xml)
Please paste it here so we can look for clues.

Yogesh

try this

hadoop fsck -Ddfs.http.address=localhost:50070 /

50070 is the default http port that the namenode runs on. The property dfs.http.address should be set in your hdfs-site.xml

Atop what Arpit has said, the format of dfs.http.address is a simple
host:port, and should not be http://host:port (which you may have set
