             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}}.
