re-install on a node - after cleaning up

re-install on a node - after cleaning up

Expert Contributor

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)

are you using Ambari? And if so, is the Ambari agent still up and running on the node?

I used the output from the cleanup-script to reinstall all the packages... everything seems to be running ok now.

I also from the output of the cleanup command the old version of hdp. Hopefully this will also fix my issue.
