	Oct 17, 2012 - See https://github.com/medined/accumulo_stackscript for an even better script. Really ignore the stuff below. Go. Scoot.

	Aug 28, 2012 - See http://affy.blogspot.com/2012/08/stackscript-for-accumulo-on-linode.html for a more concise method is configuring accumulo. I'll leave this gist unchanged for fans of history.

	My goal was to get Accumulo running on a VirtualBox Ubuntu instance. I was successful using the following steps. If a line starts with $ then it is a command-line to execute. Note that you'll need to have sudo privilege. My username was 'ubuntu'. If you are using a different username, you'll need to change the process a little bit. I'll try to point out where.

senthil245 / JDK 1.6 Installation in Ubuntu

Created July 27, 2013 02:16

Step by step installation of JDK 1.6 in Ubuntu

	Install Java JDK 6.0 update 31 on Ubuntu 12.04 LTS

	Introduction
	The first question is why are we installing an old JDK. The answer is that Oracle JDK 6.0 update 31 is the JDK recommended by Cloudera when installing CDH4 (Cloudera Distribution Hadoop v4).

	This is an update to an older version of this post. Mainly I have changed the JDK from 1.6.0_26 to 1.6.0_31 as this is the recommended JDK for CDH4 .

	Install Java
	I have a 64 bit version of Ubuntu 12.04 LTS installed, so the instructions below only apply to this OS.
