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.

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?
