Hello,

We removed a DC using instructions from 
https://docs.datastax.com/en/cassandra/2.1/cassandra/operations/ops_decomission_dc_t.html

After all nodes were gone,


1.       System.peers don't have an entry for the nodes that were removed. 
(confirmed via a cqlsh query with consistency all)

2.       Nodetool describecluster don't show them

3.       Nodetool gossipinfo show them as "LEFT".

However, logs continue to spew below and restarting the node doesn't get rid of 
this. I am thinking a rolling restart of all nodes might fix it, but I am 
curious as to where is this information still held ? I don't think this is 
causing any badness to the cluster, but I would like to get rid of this if 
possible.
