Re: error copying file from local to hadoop fs
It would appear that your HDFS set up is not functioning properly.
Please try to shut down HDFS (stop-all.sh).. waiting for a bit (5 mins) and
restarting HDFS (start-all.sh).

If that does not work, you might have to reformat the NameNode (after
shutting down HDFS again).
