Failing "Deploy Client Configuration" for HDFS service, after deletion of 1 data node

One of my datanodes' local data disks failed and are in some wierd state.  The HDFS activity was going into the directory of the mount points in the local file system which caused it to fill to 98%.  The data node wasnt dead but could not decommision, remove him or delete him from the "hosts" menu.  Every service except the HDFS service could be brought down.  The message I keep getting even now, is "Pending Command".  The way I deleted the node was to "delete" from each service.  Now, I get the Stale Configuration message, I try to deploy the configuration, I get the "pending Command" message or this from the topology-map

 

File: hadoop-conf/topology.map
The datanode that was deleted is still in that map.  I cannot show the output for security reasons.
 
Questions:
 
1. How do I cleanup the vestiges of the deleted datanode?
2. I will be replacing the server and bring another server with the same name?
 
Will #2 fix #1?
 
Any suggestions?
 
Thanks,
Anant

Re: Failing "Deploy Client Configuration" for HDFS service, after deletion of 1 data node

I shut the cluster down, rebooted the cloudera manager, restarted the cluster.  The problem went away.  The vestiges of the old server is gone and I have successfully done the client deployment as per CM request.
