I was having an issue with old libraries being used instead of the new ones.
I was having this issue but its solution didn't work for me.
So I looked for a way to clean up the old files and found this:
Well it actually got things a little to clean and now my 1 node has everything uninstalled on it... so what the best path forward from here? I still have the /usr/hdp directory? Is that any good or am i screwed and should just decommission it and then bring it back as a "new node"? (Yes the node still appears to be up as the scripts to stop the services have been deleted)
I used the output from the cleanup-script to reinstall all the packages... everything seems to be running ok now.
