             Summary: Removing and re-adding hosts makes database inconsitent
                 Key: AMBARI-17219
                 URL: https://issues.apache.org/jira/browse/AMBARI-17219
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
            Reporter: Daniel Gergely
            Assignee: Daniel Gergely
            Priority: Critical
             Fix For: 2.4.0, 2.2-next, 2.5.0


When a host is removed, it is necessary to have all the components stopped and removed, before the host itself can be deleted.
If a host component is not stopped, it is not allowed to be removed, so the host itself cannot be removed. However if re-adding the host is tried, even if it is still in the cluster, a row is inserted to topology_host_info table. Multiple lines of the same host in that table is incorrect, so topology validation fails.

Expected behaviour: if host is still in the cluster, a duplicate should not be able to be persisted in any of the related tables.
