[jira] [Commented] (CASSANDRA-15912) Occasional NEW_NODE event sent
instead of NODE_UP in dTest
[ https://issues.apache.org/jira/browse/CASSANDRA-15912?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17153558#comment-17153558 ]
Berenguer Blasi commented on CASSANDRA-15912:
---------------------------------------------
The original problem was that the node2 restart could happen before the original NEW_NODE had been sent, so upon node2 becoming UP again it would get that NEW_NODE on top. Waiting to restart once all notifications have gone through fixes the issue.
No CI runs as it would be an overkill. It failed and now passes locally: repro'ed against 3.0, 3.11 and 4.0.

> A new test for topology events in CASSANDRA-15677 is occasionally failing due to a NEW_NODE event sent instead of NODE_UP.
> For instance: [https://app.circleci.com/pipelines/github/jasonstack/cassandra/231/workflows/cdf55335-c876-450b-8bf9-1d778a2df806/jobs/2240]
> Previously topology events were not been sent at all, so it is possible that this is a long standing bug.
