I have reviewed the `Hama installation guide`, comments are in the document itself. The document is a nice start.
Michael Noll (http://www.michael-noll.com) does a good job on Hadoop installation instructions and the same have been used in the Hama Guide. Instead of repeating the instructions, we can leave the HDFS instructions from the Hama guide and refer to Michael's blog. Just wanted to avoid having another stale document. Also, Michael had been updating the Hadoop articles in reference on a regular basis. Praveen
