Summary: log-cleaner thread terminates due to java.lang.IllegalStateException Key: KAFKA-6762 URL: https://issues.apache.org/jira/browse/KAFKA-6762 Project: Kafka Issue Type: Bug Components: core Affects Versions: 1.0.0 Environment: os: GNU/Linux arch: x86_64 Kernel: 4.9.77 jvm: OpenJDK 1.8.0 Reporter: Ricardo Bartolome We are experiencing some problems with kafka log-cleaner thread on Kafka 1.0.0. We have planned to update this cluster to 1.1.0 by next week in order to fix KAFKA-6683, but until then we can only confirm that it happens in 1.0.0. log-cleaner thread crashes after a while with the following error: {code:java} [2018-03-28 11:14:40,199] INFO Cleaner 0: Beginning cleaning of log __consumer_offsets-31.

(kafka.server.KafkaServer) {code} The clients (sprint-kafka 2.1.4 that provides kafka-clients 1.0.x) have the following configuration which is: * max.partition.fetch.bytes = 1048576 While looks like increasing the message size might do the trick, we are concerned that this happens again as soon as a customers start publishing messages closer to the message.max.bytes limit. We decided to open this bug report because we think something might be wrong if message.max.bytes is 1MB and the log-cleaner throws an exception while compacting messages on __consumer_offsets because it find messages that are bigger than that. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
