I have been successful in getting SSH configured. I am also able to start a namenode, secondary namenode, tasktracker, jobtracker and datanode as evidenced by the response I get from jps. However, when I attempt to interact with the file system in any way such as the simple command hadoop fs -ls, the system hangs. So it appears to me that some communication is not occurring properly. Does anyone have any suggestions what I look into in order to fix this problem? Thanks in advance. -Jon
