Uninstall and reinstall CDH

Uninstall and reinstall CDH

Explorer

I am having issues with having an extra version of cdh on one of the hosts (both 5.5.1 and 5.5.2)  which is not allowing me to complete installing a cluster (see earlier thread by me on this issue).

 

So how do I totally uninstall CDH on the machines and reinstall them.

 

Appreciate the feedback.

I followed below process to un-install CDH completely.

Note: After complete un-installation don't forget to delete /dfs/nn data otherwise while formatting namenode it will not format untill deleting old namenode data
