Node1 Still appeared in the Host List after decommissioned it

[#1]

Hi Guys,
I have Follow all the step that were needed to decommission a node.
but after all steps :
1. Decommission the services
2. Delete Host from Cluster
3. Delete all packages that were installed.
but when i write the command :
"Cat /etc/Host"
that specific node "Node1" still appearing in the list ?
is that ok or i have missing something ?
NOTE : Particular Node "Node1" successfully removed from the list of Ambari Hosts.

@Mudassar Hussain,

Ambari does not manage /etc/hosts file. You should manually delete the entry from /etc/hosts file. If you want to see if the host is deleted or not , you can call Ambari REST api and check the response

curl -k -u {username}:{password} -H "X-Requested-By:ambari" http://{ambari-host}:{ambari-port}/api/v1/hosts

If the above call doesn't return the deleted host , then you can confirm that the host is deleted.

Thanks,

Aditya
