stuck due to assignment validation failed
Luke Chen created KAFKA-13406:
---------------------------------
Summary: Cooperative sticky assignor got stuck due to assignment validation failed
Key: KAFKA-13406
URL: https://issues.apache.org/jira/browse/KAFKA-13406
Project: Kafka
Issue Type: Bug
Components: clients
Affects Versions: 3.0.0
Reporter: Luke Chen
Assignee: Luke Chen
We'll do validateCooperativeAssignment for cooperative assignor, where we validate if there are previously owned partitions directly transfer to other consumers without "revoke" step. However, the "ownedPartition" in subscription might contain out-of-dated data, which might cause the validation always failure.
We should consider the fix it by deserializing the subscription userData for generation info in validateCooperationAssignment.
