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
Her hesitation to broadcast his full name widely is consistent with psychiatric ethics regarding self-disclosure. In therapy and public education, self-disclosure is only utilized when it benefits the client or audience. Since the name of her husband offers no therapeutic value to her viewers, its relative obscurity is a professional boundary, not an evasion.
This list demonstrates that the name "Dr. Shalini" is shared by many dedicated professionals across the globe. The marital details of these individuals are not typically part of their public professional records.

You will find detailed profiles for psychiatrists like Dr. Shalini Janarthanan on platforms like Apollo Hospitals, Dr. Shalini Chawla on Psychology Today, and Dr. Shalini Varma on Healthgrades. However, these professional listings are strictly for medical credentials, areas of expertise, and clinical approaches—not for disclosing personal relationships.
The identity of Dr. Shalini’s husband as "Dr. Mandal" suggests a partnership that may be rooted in shared intellectual or professional understanding. In the medical community, marriages often thrive on mutual respect for the demanding schedules and emotional labor required by the profession. This list demonstrates that the name "Dr
In the search results, a husband’s name is only mentioned in specific, publicly documented cases:
The debate around searching for a female doctor’s husband’s name also touches on issues of professional identity and gender norms. A common question is: Would people be equally likely to search for a male doctor's wife?
Understanding the reason behind the search is as important as the answer. People look for this information for several reasons:
The socio-psychological mechanics of .

one address per line line.
If needed update /etc/hosts according to Hadoop tutorial hints.
Once done, propagate the setup throw the cluster:

That's the end of the journey: enjoy your new HBase cluster!
