Decomissioning a NodeManager in HDP 2.6.1

I am trying to decommission a data node. I started by decommissioning the regionserver, and the nodemanger. I have 7 nodes in the cluster. When I followed the steps to remove the one nodemanager it says it was successful. Even though it says 1 was decommissioned 7 are still showing as active. How do I resolve?

Seems ambari database not updated. Can you restart ambari-server and ambari-agent from the decommission nodemanager host and check.
If issues still persist you can revert the changes (Recommission NodeManagers) then decommission it and check.
