Our cluster was upgraded from HDP 2.3.0 to 2.3.2. We’re trying to determine the best way to remove the old software stack.
Is there any supported way to remove all references to HDP 2.3.0 from Ambari?
Is the host-level cleanup accomplished by uninstalling any old package versions and removing /usr/hdp/2.3.0.0-2557? Will there be anything referencing directories under 2.3.0.0-2557 post-upgrade?
