Uwe Eisele commented on KAFKA-6762: ----------------------------------- After a restart of the broker, log-cleaner thread runs in the same problem again. During debugging of the log cleaner we saw that the affected log segement only contains deletable control batches in at least the first 1000012 bytes. In this case the log cleaner states that zero messages have been read and finally throws the IllegalStateExeption. It seems that the log cleaner can not handle larger chunks of a segment that only contain deletable records. {code:java} 092 class LogCleaner ... { ... 558 private[log] def cleanInto(...) { 595 while (position < sourceRecords.sizeInBytes) { ... 601 sourceRecords.readInto(readBuffer, position) 602 val records = MemoryRecords.readableRecords(readBuffer) ... 604 val result = records.filterTo(topicPartition, logCleanerFilter, writeBuffer, maxLogMessageSize, decompressionBufferSupplier) //in this case an empty result with zero read messages is returned, though the read buffer contains records (as mentioned above all of them are deletable control batches) ... 626 if (readBuffer.limit() > 0 && result.messagesRead == 0) 627 growBuffers(maxLogMessageSize) // throws the IllegalStateException if the readBuffer has reached the max messages size 628 } ... {code} The reason that no records are returned in the filter method is the following code block in the MemoryRecords class: {code:java} 141 private static FilterResult filterTo(...) { ... 154 for (MutableRecordBatch batch : batches) { 155 bytesRead += batch.sizeInBytes(); 156 157 BatchRetention batchRetention = filter.checkBatchRetention(batch); 158 if (batchRetention == BatchRetention.DELETE) 159 continue; {code} The segment which caused this problem can be found here [^__consumer_offsets-9_00000000000000000000.tar.xz] . > 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 > Priority: Major > Attachments: __consumer_offsets-9_00000000000000000000.tar.xz > > > We are experiencing some problems with kafka log-cleaner thread on Kafka > 1.0.0.
