Ewen Cheslack-Postava commented on KAFKA-4558: ---------------------------------------------- And this is also happening, albeit less frequently, on the 3.1.x branch: http://confluent-kafka-0-10-1-system-test-results.s3-us-west-2.amazonaws.com/2016-12-25--001.1482666294--apache--0.10.1--8c62858/report.html > throttling_test fails if the producer starts too fast. > ------------------------------------------------------ > > Key: KAFKA-4558 > URL: https://issues.apache.org/jira/browse/KAFKA-4558 > Project: Kafka > Issue Type: Bug > Reporter: Apurva Mehta > Assignee: Apurva Mehta > > As described in https://issues.apache.org/jira/browse/KAFKA-4526, the > throttling test will fail if the producer in the produce-consume-validate > loop starts up before the consumer is fully initialized. > We need to block the start of the producer until the consumer is ready to go. > The current plan is to poll the consumer for a particular metric (like, for > instance, partition assignment) which will act as a good proxy for successful > initialization. Currently, we just check for the existence of a process with > the PID, which is not a strong enough check, causing the test to fail > intermittently. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
