             Summary: Delete a host from Ambari cluster is not clean; fails to re-add the same host
                 Key: AMBARI-10167
                 URL: https://issues.apache.org/jira/browse/AMBARI-10167
             Project: Ambari
          Issue Type: Story
          Components: ambari-server
    Affects Versions: 1.7.0
            Reporter: Alejandro Fernandez
            Assignee: Alejandro Fernandez
             Fix For: 2.1.0


Deleting a host from the UI only removes it from the mapping to a cluster.
The host still exists at the hosts endpoint, and all of the historic data maintains intact; config overrides, config groups, host state, host version, host role command logs, etc.

This causes two problems.
1. If a host is removed from a cluster and its underlying environment changes (OS, IP, network card, etc), and is re-added to the cluster, then it still maintains the old information that is incorrect.
2. If host x dies, and is removed from the cluster, there is no way for a new host to take over its hostname.
