--------------------------------------
Summary: High CPU caused by timeout overflow in WorkerCoordinator
Key: KAFKA-4290
URL: https://issues.apache.org/jira/browse/KAFKA-4290
Project: Kafka
Issue Type: Bug
Components: KafkaConnect
Reporter: Jason Gustafson
Assignee: Jason Gustafson
Priority: Blocker
Fix For: 0.10.1.0
The timeout passed to {{WorkerCoordinator.poll()}} can overflow if large enough
because we add it to the current time in order to calculate the call's
deadline. This shortcuts the poll loop and results in a very tight event loop
which can saturate a CPU. We hit this case out of the box because Connect uses
a default timeout of {{Long.MAX_VALUE}}.
