The Pseudo Cluster is back up and running and able to run java programs, in this case, the wordcount example. Backups have been taken (again, hopefully whilst stable!) the previous tutorials needed some tweaking as there were missing bits or parts that have changed in the space of a month...
Two major issues were to be found in the reinstall - Java, which is now working, and Gedit... for some reason as the admin user I could not run GEDIT from the command prompt... and I could not edit the Hduser files that needed edited, but by logging out as the admin and logging in as hduser (this is after setting hduser up as an admin!) then gedit worked fine in the hduser account...
CONFUSED! but whatever, it works now :)

Installing sun-java6-jdk on Ubuntu 11.10
Intro Waffle:
*****
Frustratingly, I have been banging my head against a wall trying to get beeswax working in an isolated install of Linux on Virtual-Box. The issue being that I could not get Java6-jdk downloaded and installed. I had originally tried this on a working image of linux that had my previous hadoop working on, but since it would not work, I tailed off... I did do a backup of the original install but that clone corrupted... so now I am sat here with no operational honours project work and am forced to restart.
On restarting I hit that Java wall again, this time with some more determined searching, I found that it had been removed from some repositories, e.g Canonical. Here is what I uncovered during the search and tried, and it worked. Hopefully it will work for you too if you stumble over this trying to find a solution to a similar issue.
*****
Installing:
$ sudo apt-get install python-software-properties
$ sudo add-apt-repository ppa:ferramroberto/java
(I dont know how long this link will be hosted, but as of time of posting - this works, and has been hosted here for a few months.)
$ sudo apt-get update
$ sudo apt-get install sun-java6-jdk
With that done - its now a good time to test how efficient my own tutorials on setting up hadoop are.
