Generally this means you are failing to connect to the NameNode of your HDFS system. I've seen this because of a version incompatibility between your client and your server, or because of a misconfigured NameNode location in your config files. I would check the version of Hadoop installed in the HADOOP_HOME you are using on the launching machine and the version of Hadoop on your cluster. I would also check in HADOOP_HOME/conf/core-site.xml to check that the fs.default.name parameter matches the hostname and port your NameNode are running on.
