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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
