How to remove old HDP stack after upgrading HDP

[#1]

Hello Guys!

I updated HDP from 3.1.0.0-78 to 3.1.5.6189-1 as well as Ambari from 2.7.3 to 2.7.5.

I want to remove the old stack of HDP as the files are still on the servers.

Is there any official guide for this move?

Hi @rki_ , Really thank you for sharing these links with me.
I've gone through all of them. It seems the removing script has some bugs.

I'm curious about whether any official Docs mention the script.

Hi @fengsh Yes, The remove script indeed has few bugs using curl which was picked up from AMBARI-18435 but this curl call is not officially supported and as such we don't have an official doc on this.

The other option to remove the older stack with "yum remove <version>" command, specifying the exact version you want to remove should get the job done.

You can also verify the list of packages to be removed using (please be thorough!):

# yum list installed | grep -P 'version'

Additionally, please verify the symlinks in the "/usr/hdp/current/" folder are pointing to the correct location.
