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

Education in Malaysia is a blend of cultural diversity and structured academic rigor, characterized by a mix of public, private, and international institutions.
Malaysia is a nation celebrated for its cultural kaleidoscope—where Malay, Chinese, Indian, and indigenous traditions intermingle. This diversity is not merely a social trait; it is the very backbone of the country’s education system. For students, parents, and expatriates looking to understand the country, navigating the world of Malaysian education and school life reveals a unique blend of rigorous academics, multi-lingual immersion, and a collective emphasis on discipline and respect.

Students generally report a positive school life experience, citing friendships, extracurricular activities, and sports as highlights. However, some students express concerns about the pressure to perform well academically, the lack of autonomy in choosing subjects, and the rigid school rules.
Taken at the end of Form 5 (age 17). It is equivalent to a GCE O-Level and is crucial for tertiary education. Co-Curriculum and Discipline Co-curricular activities are mandatory and graded. Uniform Units: Scouts, Girl Guides, Red Crescent. Clubs/Societies: Debate, Science, Art. Sports: Football, Badminton, Netball.
The Malaysian education system is divided into several stages: preschool, primary, secondary, and post-secondary. The system is overseen by the Ministry of Education (MOE), which sets national standards and policies. The education structure is as follows:

While the system is robust, it faces evolving challenges that have sparked national debate:

If needed update /etc/hosts according to Hadoop tutorial hints.
