Ray Chiang updated KAFKA-4238: ------------------------------ Component/s: consumer admin > consumer-subscription not working, when accessing a newly created topic > immediately after its creation with the AdminUtils > -------------------------------------------------------------------------------------------------------------------------- > > Key: KAFKA-4238 > URL: https://issues.apache.org/jira/browse/KAFKA-4238 > Project: Kafka > Issue Type: Bug > Components: admin, consumer > Affects Versions: 0.10.0.0, 0.10.0.1 > Reporter: Florian Witteler > Priority: Major > > I created a test-project to reproduce the bug. > https://github.com/FloWi/kafka-topic-creation-bug > We use a docker container that creates a fresh topic before a testsuite gets > executed (see {{trait FreshKafkaTopics}}). That trait uses the AdminUtils to > create the topic. > If we access the newly created topic directly after its creation, the > subscriber is broken. It sometimes works though (<5%), so it seems to be a > race-condition. > If I put a {{Thread.sleep(1000)}} after the topic-creation, everything's fine > though. > So, the problem is twofold: > - {{AdminUtils.createTopic}} should block until the topic-creation is > completed > - {{new KafkaConsumer[String, > String](props).subscribe(util.Arrays.asList(topic))}} should throw an > exception, when the topic is "not ready" -- This message was sent by Atlassian JIRA (v7.6.3#76005)
