How to uninstall Hadoop 1.0.0

I set up my Hadoop clusters with Hadoop 2.0.2. Then, today I tried to test 1.0.0. So I downloaded the deb file from the Hadoop website and installed it: It did mess up everything.

Now, when I type "which -a hadoop" I get 2 results

So the question is: how to get rid off of Hadoop 1.0.0 completely?

I struggled through this for longer than a while and then decided to share it here:

The trick is to basically delete all the symlinks pointing back to locations where HDP components reside since that is what causes 80% of the problem. Here is a step by step tutorial for that:

Hope that helps!

> $HADOOP_HOME
> /home/shiv/hadoop
> sudo rm -r /home/shiv/hadoop

And Hadoop is uninstalled!

Try using dpkg -r hadoop; this should remove the Hadoop package from the system, but leave the config files intact. If you want to lose the config files as well, try dpkg -P hadoop instead.
