nodetool decommision is behaving strange

I tried removing a node from a cluster by issuing "nodetool decommission" and have seen netstats to find out how much data is being distributed to other nodes which is all fine.
After the node has been decommissioned, I could see the status of few nodes in a cluster as 'UD' when I run nodetool status on few nodes(Not the one I decommissioned) and few nodes are showing 'UN' as status
I'm quite confused about why the status on nodes is showing such behavior, and not same on all nodes after the decommissioned the node.

Am I missing any steps before and after?
Any comments/Help is highly appreciated!

If gossip information is not the same in all nodes, then you should do a rolling restart on the cluster. That will make gossip reset in all nodes.

Was the node you removed a seed node? If it was, don't forget to remove the IP from the cassandra.yaml in all nodes.
