On a recent project, I ran into an issue with Python Selenium webdriver. There's no easy way to open a new tab, grab whatever you need and return to original window opener.

Here's a couple people who ran into the same complication:

• http://stackoverflow.com/questions/17547473/how-to-open-a-new-tab-using-selenium-webdriver
• http://stackoverflow.com/questions/6421988/webdriver-open-new-tab/9122450#9122450
• https://groups.google.com/forum/#!topic/selenium-users/kah4iEPRopc
• ... and many many more.

So, after many minutes (read about an hour) of searching, I decided to do find a quick solution to this problem.

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.
