devinbost opened a new issue #6258: (Flaky-Test) Possible Race Condition - Namespace already exists URL: https://github.com/apache/pulsar/issues/6258 I've actually experienced intermittent (random) issues in production that have given the message "Namespace already exists," but we never captured broker logs when this has happened. This is an intermittent error that appears to be a race condition or concurrency issue, rather than an issue with just the test: ``` [ERROR] Tests run: 20, Failures: 1, Errors: 0, Skipped: 1, Time elapsed: 345.803 s <<< FAILURE! - in org.apache.pulsar.broker.service.ReplicatorTest 464[ERROR] testReplicatedCluster(org.apache.pulsar.broker.service.ReplicatorTest) Time elapsed: 0.023 s <<< FAILURE! 465org.apache.pulsar.client.admin.PulsarAdminException$ConflictException: Namespace already exists ``` This may reflect intermittent issues that are happening in production. The logs can be seen here: https://github.com/apache/pulsar/pull/6202/checks?check_run_id=431093396 I've also attached the logs.
