Seweryn Habdank-Wojewodzki commented on KAFKA-5530: --------------------------------------------------- Logs are made fresh after rebuild SW with K 0.11.0.0. I will also further investigate what can be the root cause of the behavior. > Balancer is dancing with KStream all the time, and due to that Kafka cannot > work :-) > ------------------------------------------------------------------------------------ > > Key: KAFKA-5530 > URL: https://issues.apache.org/jira/browse/KAFKA-5530 > Project: Kafka > Issue Type: Bug > Affects Versions: 0.10.2.0, 0.10.2.1, 0.11.0.0 > Environment: Linux, Windows > Reporter: Seweryn Habdank-Wojewodzki > Attachments: streamer_20-topics_1-thread-K-0.11.0.0.log.zip, > streamer_20-topics_4-threads-K-0.11.0.0.log.zip, > streamer_2-topics_1-thread-K-0.11.0.0.log.zip, > streamer_2-topics_4_threads-K-0.11.0.0.log.zip > > > Dears, > There are problems with balancer in KStreams (v. 0.10.2.x), when > _num.stream.threads_ is bigger than 1 and the number of the input topics are > bigger than 1. > I am doing more less such a setup in the code: > {code:java} > // loop over the inTopicName(s) { > KStream<String, String> stringInput = kBuilder.stream( STRING_SERDE, > STRING_SERDE, inTopicName ); > stringInput.filter( streamFilter::passOrFilterMessages ).map( ndmNormalizer > ).to( outTopicName ); > // } end of loop > streams = new KafkaStreams( kBuilder, streamsConfig ); > streams.cleanUp(); > streams.start(); > {code} > And if there are *_num.stream.threads=4_* but there are 2 or more but less > than num.stream.threads inTopicNames, then complete application startup is > totally self-blocked, by writing endless starnge things in log and not > starting. > Even more problematic is when the nuber of topics is higher than > _num.stream.threads_ what I had commented in *KAFKA-5167 streams task gets > stuck after re-balance due to LockException*. > I am attaching logs for two scenarios: > * when: 1 < num.stream.threads < numer of topics (KAFKA-5167) > * when: 1 < numer of topics < num.stream.threads (this ticket). > I can fully reproduce the behaviour.
