Subject how to remove a dead node?
Date Sat, 01 Mar 2014 19:31:37 GMT
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?
