Brandon Williams commented on CASSANDRA-16511:
----------------------------------------------
Worth noting there are also some in-jvm dtests that can't run in parallel as
they require absolute port numbers.
> Running tests in parallel can sometimes result in port collision

> Key: CASSANDRA-16511
> URL: https://issues.apache.org/jira/browse/CASSANDRA-16511
> Project: Cassandra
> Issue Type: Bug
> Components: Test/unit
> Reporter: Jacek Lewandowski
> Assignee: Jacek Lewandowski
> Priority: Normal
> Fix For: 3.0.x, 3.11.x, 4.0.x
>
>
> When running unit tests with parallel execution we may sometimes notice the
> port collision. In this mode, test classes from the list get consecutive
> offsets which are added to native transport port, storage port and ssl
> storage port ( {{OffsetAwareConfigurationLoader}} ). However we add to the
> ports configured in {{test/conf/cassandra.yaml}} we as we can see we have the
> following default config:
> {code:java}
> storage_port: 7012
> ssl_storage_port: 7011 {code}
> This results in the situation that thread n has the same storage port as
> thread n+1 has ssl storage port. There are not much such tests, but we can
> see {{ConnectionTests}} failing frequently because of that.
> The other problem is that {{OffsetAwareConfigurationLoader}} does not adjust
> native transport ssl port.
