-------------------------------------

             Summary: Fix exceptions when enabling gossip on proxy nodes.
                 Key: CASSANDRA-12253
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-12253
             Project: Cassandra
          Issue Type: Bug
            Reporter: Dikang Gu
            Priority: Minor
             Fix For: 2.2.x


We have a tier of Cassandra nodes running with join_ring=false flag, which we call proxy nodes, and they will never join the ring.

The problem is that sometimes we need to disable and enable the gossip on those nodes, and `nodetool enablegossip` throws exceptions when we do that:
