Hello , Thanks in advance for any help. In our kafka cluster a couple of partitions in __consumer_offsets and 1 regular topic getting data corruption issue while replicas trying to read from leader. Similar messages for other partitions as well .
[2022-02-28 21:57:29,941] ERROR [ReplicaFetcher replicaId=6, leaderId=1, fetcherId=2] Found invalid messages during fetch for partition __consumer_offsets-10 offset 108845487 (kafka.server.ReplicaFetcherThread) org.apache.kafka.common.errors.CorruptRecordException: Record is corrupt (stored crc = 1524235439) in topic partition __consumer_offsets-10 another topic partitions with same errors [2022-02-28 22:17:00,235] ERROR [ReplicaFetcher replicaId=6, leaderId=1, fetcherId=0] Found invalid messages during fetch for partition px-11351-xxxxxx-a56c642-0 offset 11746872 (kafka.server.ReplicaFetcherThread) org.apache.kafka.common.errors.CorruptRecordException: Record is corrupt (stored crc = 475179617) in topic partition px-11351-xxxxxx-a56c642-0. I have verified all infrastructure, dish network and system for any errors found and nothing found. I am not sure why it is happening or how to troubleshoot. Bellow is output of the message from DumpLogSegments , $ /opt/ns/kafka/bin/kafka-run-class.sh kafka.tools.DumpLogSegments --verify-index-only --deep-iteration --files ./00000000000011324034.log | grep 11746872 baseOffset: 11746872 lastOffset: 11746872 count: 1 baseSequence: 50278 lastSequence: 50278 producerId: 17035 producerEpoch: 0 partitionLeaderEpoch: 8 isTransactional: false isControl: false position: 252530345 CreateTime: 1645886348240 size: 647 magic: 2 compresscodec: SNAPPY crc: 475179617 isvalid: true | offset: 11746872 CreateTime: 1645886348240 keysize: 54 valuesize: 637 sequence: 50278 headerKeys: [] Does anyone know what would cause this and if possible, how to fix the corruption ?
