--------------------------------------
Summary: Blueprint deployment throwing NPE when there is a config
marked as deleted
Key: AMBARI-17793
URL: https://issues.apache.org/jira/browse/AMBARI-17793
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.4.0
Reporter: Jayush Luniya
Assignee: Jayush Luniya
Priority: Critical
Fix For: 2.4.0
Discovered when deploying a custom stack
Ambari accepts the blueprint and starts the deploy job but when you open the
UI, the job just sits in pending state and status says waiting for hosts to be
added to host group
