C0urante commented on pull request #7734: KAFKA-9223: Mask exit procedure in
rebalance integration test to prevent call to System::exit
URL: https://github.com/apache/kafka/pull/7734
We've been encountering some build instability that appears to be due to the
`RebalanceSourceConnectorsIntegrationTest` class. Somehow, that test is causing
an ungraceful shutdown of one or more of its embedded Connect workers, which
then in turn invoke `Exit::exit`. The Connect integration test framework has
support for overriding the behavior of `Exit::exit` to prevent it from calling
`System::exit`; the changes here use that feature to help bring back build
stability.
Now, if the embedded Connect worker fails to shut down gracefully, a warning
is logged but the test still passes and (more importantly), `System::exit` is
never invoked.
If approved, this fix should be backported through to 2.3, when the test was
introduced.
