Description

When a host is removed from the cluster and later from ambari there's a chance the agent registers back to the ambari server before the agent is stopped.

Stopping the machine running the agent without the host being deleted again leads to an inconsistent state in the ambari-server due to cached state.

Resolution:
The cached resources get cleared on host delete event.
