ASF GitHub Bot commented on KAFKA-5449:
---------------------------------------
GitHub user apurvam opened a pull request:
https://github.com/apache/kafka/pull/3346
MINOR: Cleanups for TransactionsTest
The motivation is that KAFKA-5449 seems to indicate that producer instances
can be shared across tests, and that producers from one test seem to be hitting
brokers in another test.
So this patch does two things:
# Make transactionsTest use random ports in each test case.
# Clear producers and consumers between tests.
You can merge this pull request into a Git repository by running:
