------------------------------------
Summary: Fix ELR metadata version issues
Key: KAFKA-18634
URL: https://issues.apache.org/jira/browse/KAFKA-18634
Project: Kafka
Issue Type: Bug
Reporter: Colin McCabe
Assignee: Calvin Liu
Fix several ELR metadata version issues for 4.0
- Several places in the code just check MetadataVersion.isElrSupported rather
than looking at whether the eligible.leader.replicas.version feature is
enabled. We need to check the feature and not do ELR stuff when ELR is turned
off.
- The documentation for MetadataVersion.IBP_4_0_IV1 should say which metadata
records changed. Specifically, PartitionRecord, PartitionChangeRecord. It
should also mention that ClearElrRecord was added in this MV.
- IBP_4_0_IV1 needs to be marked as stable.
