This tutorial is a sequel of of Matteo Lissandrini's "Installing HDFS and Hadoop 2.X on a Multi-node cluster with Ubuntu 14.0.
That guide can also be used to install Hadoop 1.x (with minor if none modification); in this work we will assume that you have followed that tutorial and have installed Hadoop 1.x and HDFS.
Even thought HBase 0.94.x can run against both Hadoop 1.x and 2.x versions (see HBase 0.94 book) we highly recommend to use Hadoop 1.x for HBase 0.x and Hadoop 2.x for HBase 1.x and 2.x.
We wish also to inform you that also this tutorial can be applied to HBase 1.x and 2.x (with minor if none modification).
The following steps will be needed only once. Download HBase 0.94.X stable, to do so navigate in the List of Mirrors select one and decide which version to download. For the sake of simplicity from now on we will assume tho have chosen version 0.94.27.
For example wget can be used:
# from eu wget https://www.eu.apache.org/dist/hbase/hbase-0.94.27/hbase-0.94.27.tar.gz # from us wget https://www.us.apache.org/dist/hbase/hbase-0.94.27/hbase-0.94.27.tar.gz
Then extract the tar to the final installation directory, fix also permission and create a version agnostic symlink.
In this tutorial we will use the standard /usr/local/ as installation directory but obviously you are free to chose the one you prefer.
# extract & copy sudo tar -zxf hbase-0.94.27.tar.gz -C /usr/local/ # fix permission sudo chown -R hduser:hadoop /usr/local/hbase-hbase-0.94.27/ # create symlink sudo ln -s /usr/local/hbase-0.94.27/ /usr/local/hbase

Finally configure and initialize the other cluster nodes.
List the machines that will act as region server in conf/regionservers,
one address per line line.
If needed update /etc/hosts according to Hadoop tutorial hints.
Once done, propagate the setup throw the cluster:
#!/bin/bash
# Build configured HBase tar.
mkdir -p /tmp/distr/
tar -czf /tmp/distr/hbase.tgz /usr/local/hbase-0.94.27
# Distribute to each region node
while IFS='' read -r node_ip; do
scp /etc/hosts hduser@$node_ip:~/
scp ~/.profile ~/.vimrc hduser@$node_ip:~/
scp hbase.tgz hduser@$node_ip:~/
ssh -o StrictHostKeyChecking=no -tt hduser@$node_ip <<EOF
sudo mv $HOME/hosts /etc/
# Install & link & fix permission
sudo tar -zxf $HOME/hbase.tgz -C /
sudo ln -s /usr/local/hbase-0.94.27 /usr/local/hbase
sudo chown -R hduser:hadoop /usr/local/hbase*
# Create zookeeper directory (even if not needed)
sudo mkdir -p /usr/local/zookeeper
# Fix permission
sudo chown -R hduser:hadoop /usr/local/zookeeper
# Raise the limit for max opened files (DB srv)
sudo sysctl -w fs.file-max=100000
# Required due to -tt option
exit
EOF
done < /usr/local/hbase/conf/regionservers
That's the end of the journey: enjoy your new HBase cluster!
Start it running start-hbase.sh
