We have a node that died and had to be rebuilt. However, its status is still showing in the dfsadmin report
hdfs dfsadmin -report

Ambari doesn't show it at all in the hosts. How do I remove it so I can re-add it without conflict?

Actually it does show in Ambari, but the only time I've seen it is when adding a new host it shows in the "other registered hosts" list.
