> *Problem Statement*:
> Allow user to bring back a host/VM that is dead with the same hostname and allow an action to recover the state of the host to what it was before the incident
> *Solution*:
> - User gets the host/VM back with same hostname (different IP address is ok)
> - The UI state would be INSTALLED for all host components as soon as the host starts heart beating
> - User will initiate a Recover user action that will do the following (batch operation):
> -- Move the state of the components back to INIT (allow this state transition)
> {code}
> curl -H "X-Requested-By:ambari" -u admin:admin -i -X PUT -d {"RequestInfo":{"context":"Reset All Host Components","operation_level":{"level":"HOST","cluster_name":"c1","host_names":"c6401.ambari.apahe.org"},"query":"HostRoles/component_name.in(DATANODE,NODEMANAGER,METRICS_MONITOR)"},"Body":{"HostRoles":{"state":"INIT"}}} http://c6401.ambari.apache.org:8080/api/v1/clusters/c1/hosts/c6401.ambari.apache.org/host_components
> {code}
> -- Issue an INSTALL operation on all hostcomponents (Same call as above with state = "INSTALLED")
> -- Issue a START operation on all hostcomponents (Same call as above with state = "STARTED")
> *Note*: The above operation is expected to recover the security state of the host.
