----------------------------------------
Summary: Atlas Upgrade Check
Key: AMBARI-15830
URL: https://issues.apache.org/jira/browse/AMBARI-15830
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.4.0
Reporter: Dmytro Grinenko
Fix For: 2.4.0
Atlas for HDP 2.5 will need to be a new install. Atlas does not support upgrade
(rolling upgrade or otherwise) from prior versions. It is only from HDP 2.5 on
that Atlas support express and rolling upgrades.
Because of this, it is necessary to have a pre upgrade check in Ambari that
handles this case by asking the user to uninstall Atlas prior to upgrade. After
the cluster has been upgraded, Atlas can be added to the cluster using the
Ambari add service mechanism. This will result in a clean/new install of Atlas
that will from this point on support rolling and express upgrades.
