Bradley created KAFKA-9867:
------------------------------
Summary: Log cleaner throws InvalidOffsetException for some
partitions
Key: KAFKA-9867
URL: https://issues.apache.org/jira/browse/KAFKA-9867
Project: Kafka
Issue Type: Bug
Components: log cleaner
Affects Versions: 2.4.0
Environment: AWS EC2 with data on EBS volumes.
Reporter: Bradley
About half the partitions for one topic are marked "uncleanable". This is
consistent across broker replicas – if a partition is uncleanable on one
broker, its replicas are also uncleanable.
The log-cleaner log seems to suggest out of order offsets. We've seen corrupt
indexes before, so I removed the indexes from the affected segments and let
Kafka rebuild them, but it hit the same error.
I don't know when the error first occurred because we've restarted the brokers
and rotated logs, but it is possible the broker's crashed at some point.
How can I repair these partitions?
