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
Using a reliable ensures your system remains secure, eligible for updates, and legally compliant. By utilizing official Microsoft tools, you can avoid the risks associated with counterfeit software. Always prioritize purchasing from trusted sources to ensure your license remains active for the life of your device.

Navigating the World of Microsoft Product Key Checkers Microsoft Product Key Checker
You don't need a checker if you know the red flags. Here is how to manually identify a bad key. Using a reliable ensures your system remains secure,
If a stolen key is sold and activated on multiple computers globally, Microsoft’s automated systems will instantly flag and blacklist the key, destroying your investment.
To help narrow down the best solution for your system, let me know: Are you checking a key for or Microsoft Office ?
A Microsoft Product Key Checker is a tool that helps you: Transferable to another computer (one PC at a time)
Retrieve lost keys from currently installed systems to facilitate reinstallation. Best Methods for Checking Your Microsoft Product Key
1. The Official Microsoft Account Approach (Best for Office & Digital Licenses)
If you provide more details about your specific scenario (e.g., “I have a key but don’t know which Windows version it’s for”), I can offer a more tailored walkthrough.
If a stolen key is shared or resold to multiple parties simultaneously, Microsoft's anti-piracy algorithms will flag the sudden geographic activation spikes and block the key entirely.
Shady websites log the keys you type into their forms. If you input a valid, expensive Retail or Volume key, the site operators can steal it and resell it to other buyers.
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
