[GitHub] [cassandra-dtest] rhuffy opened a new pull request, #215: CASSANDRA-18319: IP change then decommission

["rhuffy (via GitHub)" <gi...@apache.org>]

rhuffy opened a new pull request, #215:
URL: https://github.com/apache/cassandra-dtest/pull/215

   Adds a new test to reproduce the issue reported in [CASSANDRA-18319](https://issues.apache.org/jira/browse/CASSANDRA-18319).
   
   Decommissioning a node soon after changing its IP causes the old IP to be resurrected and re-added to the token ring.
   
   This test performs the following:
   - creates a 6 node cluster
   - changes the IP of Node6 from `127.0.0.6` to `127.0.0.9`
   - performs a rolling restart on the cluster
   - decommissions Node6
   - asserts that the log `"Node /127.0.0.6 is now part of the cluster"` does not appear after the rolling restart.
