[jira] [Created] (KAFKA-9824) Consumer loses partition offset and
resets post 2.4.1 version upgrade
Nitay Kufert created KAFKA-9824:
-----------------------------------
Summary: Consumer loses partition offset and resets post 2.4.1 version upgrade
Key: KAFKA-9824
URL: https://issues.apache.org/jira/browse/KAFKA-9824
Project: Kafka
Issue Type: Bug
Affects Versions: 2.4.1
Reporter: Nitay Kufert
Hello,
around 2 weeks ago we upgraded our Kafka clients & brokers to 2.4.1 (from 2.3.1),
and we started noticing a troubling behavior that we didn't see before:
Without apparent reason, a specific partition on a specific consumer loses its offset and start re-consuming the entire partition from the beginning (according to the retention).
Messages appearing on the consumer (client):
{quote}Apr 5, 2020 @ 14:54:47.327 INFO sonic-fire-attribution [Consumer clientId=consumer-fireAttributionConsumerGroup4-2, groupId=fireAttributionConsumerGroup4] Resetting offset for partition trackingSolutionAttribution-48 to offset 1216430527.{quote}

Those are the logs from the brokers at the same time (searched for "trackingSolutionAttribution-48" OR "fireAttributionConsumerGroup4")

Another way to see the same thing, from our monitoring (DD) on the partition offset:
!https://mail.google.com/mail/u/0?ui=2&ik=8f9b1ec48a&attid=0.1&permmsgid=msg-a:r-1797075611836356806&th=1714b5531deb08d9&view=fimg&sz=s0-l75-ft&attbid=ANGjdJ_EnC23byd8TemOhOsmVTdpfogSBTeh45zFq4EVB1OvXnSZeLO0yepieyKAm8OoIarKz6qGYuKh9Pp2Ck7CmUFvZj4LljcYfzbmsdMF3LYaN93F6aUIH0l1bMA&disp=emb&realattid=ii_k8n355r50|width=542,height=158!
The recovery you are seeing is after I run partition offset reset manually (using kafka-consumer-groups.sh --bootstrap-server localhost:9092 --topic trackingSolutionAttribution:57 --group fireAttributionConsumerGroup4 --reset-offsets --to-datetime 'SOME DATE')
Any idea what can be causing this? we have it happen to us at least 5 times since the upgrade, and before that, I don't remember it ever happening to us.
