[bin/hadoop fs -ls -> Bad connection to FS. command aborted]

[om...@ac.upc.edu]

Hi all,

I have a problem with the hadoop file system. When I am trying to open
it with the command line "bin/hadoop fs -ls" I receive the next message
"Bad connection to FS. command aborted". I have tried to execute the
hadoop scripts to manage that issues like, start-all, stop-all,
start-dfs, stop-dfs, etc, but I couldn't resolve the problem. Can
somebody help me?

Many thanks,
Oriol
