Hi, I am new to Hadoop, and am trying to get Hadoop started in Pseudo-distributed mode on ubuntu jaunty.
In the archives I noticed that someone had a similar issue with hadoop-0.20.0, but the logs are different. As in the quickstart guide ( http://hadoop.apache.org/common/docs/current/quickstart.html) , I configured the xml files, and set up passphraseless ssh The output of bin/hadoop namenode -format is as follows : 09/08/13 23:52:49 INFO namenode.NameNode: STARTUP_MSG: /************************************************************ STARTUP_MSG: Starting NameNode STARTUP_MSG: host = arvind-laptop/127.0.1.1 STARTUP_MSG: args = [-format] STARTUP_MSG: version = 0.19.2 STARTUP_MSG: build = https://svn.apache.org/repos/asf/hadoop/common/branches/branch-0.19 -r 789657; compiled by 'root' on Tue Jun 30 12:40:50 EDT 2009 ************************************************************/ Re-format filesystem in /tmp/hadoop-arvind/dfs/name ?

On another note, the quick start guide pointed to Cloudera's distribution of Hadoop, and they have debian package for ubuntu. Is the development plan of Apache and Cloudera same? Do both ship the same source release? Cheers, Arvind
