Thanks for your reply Harsh I checked my logs and found that namenode and datanode ID were different. May be datanode got corrupted. I removed all files from /app/tmp/dfs folder and formatted -namenode again . It started working :) Then I ran HBase on it . It worked but I got something like "You are currently running the Hmaster without HDFS append support enabled" I downloaded cloudera's cdh3 update 3 and replaced it with hadoop-0.20 . But now it says starting namenode, logging to /usr/local/hadoop-0.20.2/logs/hadoop-root-namenode-89neuron.out May not run daemons as root. Please specify HADOOP_NAMENODE_USER same for datanode,tasktracker,jobtraacker and secondary name node
I did not found documentation of installation using a tarball. I am using ubuntu 10.04. I know there are deb files for installation but I want to install from tarball.
