<tip><title>Hadoop 2.x is better than Hadoop 1.x</title>
<para>Hadoop 2.x is faster, with more features such as short-circuit reads which will help improve your
HBase random read profile as well important bug fixes that will improve your overall HBase experience.
You should run Hadoop 2. rather than Hadoop 1. if you can.
