David Dufour created KAFKA-14064: ------------------------------------ Summary: MirrorMaker2 stops task when record is too big Key: KAFKA-14064 URL: https://issues.apache.org/jira/browse/KAFKA-14064 Project: Kafka Issue Type: Improvement Components: mirrormaker Affects Versions: 2.7.1 Reporter: David Dufour
As MirrorMaker2 does currently not support shallow mirrorring ([KIP-712: Shallow Mirroring|https://wiki.apache.org/confluence/display/KAFKA/KIP-712%3A+Shallow+Mirroring]), if a producer has produced using compression in one mirrorred topic, MirrorMaker2 will get the message uncompressed at some point and if not properly tuned (typically {{{}max.request.size{}}}), it may fail with a RecordTooLargeException: org.apache.kafka.connect.errors.ConnectException: Unrecoverable exception from producer send callback at org.apache.kafka.connect.runtime.WorkerSourceTask.maybeThrowProducerSendException(WorkerSourceTask.java:284) at org.apache.kafka.connect.runtime.WorkerSourceTask.sendRecords(WorkerSourceTask.java:338) at org.apache.kafka.connect.runtime.WorkerSourceTask.execute(WorkerSourceTask.java:256) at org.apache.kafka.connect.runtime.WorkerTask.doRun(WorkerTask.java:189) at org.apache.kafka.connect.runtime.WorkerTask.run(WorkerTask.java:238) at java.base/java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:515) at java.base/java.util.concurrent.FutureTask.run(FutureTask.java:264) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1128) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628) at java.base/java.lang.Thread.run(Thread.java:829) Caused by: org.apache.kafka.common.errors.RecordTooLargeException: The message is 1049087 bytes when serialized which is larger than 1048576, which is the value of the max.request.size configuration.\n" worker_id: 'xxx.xxx.xxx.xxx:8083' The task is stopped and needs a manual restart. However, this seems to be a bit overkill because, amongst all partitions replicated by the task, only one is problematic. Stopping the replication on all partitions can make a severe impact. It would be more optimized to 'suspend' the partition involved and keep replication working for all remaining ones. -- This message was sent by Atlassian Jira (v8.20.10#820010)
