Unable to remove the dead host from Cluster

i'm unable to remove dead host which no-longer exists from the Cluster.

 

i tried deleting/removing from the cluster but after few mins it comes back , i think couldera management services is bringing back those dead host

 

could you please let me know , how could i get this resolved ?

 

for now, i have decommissioned the host and suppressed the agent status alert

Re: Unable to remove the dead host from Cluster

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.

Re: Unable to remove the dead host from Cluster

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
