Jabir: Thanks you are correct. No need to do a format on the slaves. I will update the post.

By the way, now days the easiest way to install on Ubuntu is with the cloud era packages. Assuming you just want to have a basic install and don’t plan to do any mods to the code.

Another cool way (and what we use now is with Infochimps Ironfan and Opscode Chef https://github.com/infochimps-labs/ironfan

for host in `cat slaves`
do
echo $host
scp slaves masters hdfs-site.xml hadoop-env.sh core-site.xml ${host}:/mnt/hadoop/conf
ssh $host ‘/mnt/hadoop/bin/hadoop namenode -format’
done

not sure why you formant the slaves.

running the name node -format once from any node as super user usually will format the namenode

If you are planning on accessing HBase from a Hadoop job, you’ll also need to add the zookeeper jar to hadoop’s classpath and restart the cluster. Either that or distribute zookeeper jar with the map reduce job, but that seems unlikely.

Updated to use HBase 0.20.0 Release Candidate 3. All the was needed to do was to update the code base to the release candidate. The config files are the same as described earlier.
