Namenode should log warning message when trying to start on a unformmatted system
---------------------------------------------------------------------------------

                 Key: HDFS-2662
                 URL: https://issues.apache.org/jira/browse/HDFS-2662
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: name-node
    Affects Versions: 0.20.203.0
         Environment: Single-node cluster on OS X 10.7 (Lion)
            Reporter: William McNeill
            Priority: Minor


When you try to start the namenode for a system that does not have a formatted DFS, it fails
silently without any indication that the lack of formatting was the problem. I tried to run
start-dfs.sh on a single-node cluster with an unformatted HDFS. The namenode failed to start,
but generated no warning messages, and its log was empty. After running "hadoop namenode -format"
everything worked.

Details in this thread: http://mail-archives.apache.org/mod_mbox/hadoop-common-user/201112.mbox/%3CCAN9z%2BopAn-t_f3FRC%3DDtV0n0ysoKd3Fek-fJPb68PMThiPooKg%40mail.gmail.com%3E

This is a difficult problem to diagnose because the namenode gives you no feedback. It would
be better if it printed an error message to its log file.
