Hello,
I am new to hadoop. I am using hadoop 0.17, I am trying to run it
Pseudo-Distributed.
I get NotReplicatedYetException while executing 'bin/hadoop dfs' commands.
The following is the partial text of the exception
08/12/31 02:38:26 INFO dfs.DFSClient:

I googled but did not find a remedy, and the mailing list archive did
not have a search.
Kindly help me fix the exception.
