Guozhang Wang created KAFKA-3882:
------------------------------------
Summary: Integration failures on low-end machines
Key: KAFKA-3882
URL: https://issues.apache.org/jira/browse/KAFKA-3882
Project: Kafka
Issue Type: Bug
Components: streams, unit tests
Reporter: Guozhang Wang
Assignee: Guozhang Wang
I now consistently saw some integration failures on my laptop due to no records
ever been produced in 30 / 60 seconds (my laptop only has 4GB and when running
the unit test today it is burning all CPUs / memory btw):
