How "dead" is the host? If the system is still able to start the operating system then the Cloudera Manager Agent may be running. This will cause it to heartbeat to the Cloudera Manager Server and will show up in the lists of hosts.

If this is the case, remove the cloudera-manager-agent package from the dead host. You should be able to delete the host from Cloudera Manager without it returning.

go to /var/lib/cloudera-scm-agent/ and remove all the 3 files (uuid, cm_guid, response.avro)

stop the cloudera-manager-agent and remove this host details from "/etc/hosts" for all other nodes . This should solve the problem, let us know if still any issues.

Thanks
