A. Sophie Blee-Goldman commented on KAFKA-13406: ------------------------------------------------ Yes, we should definitely get this fix into 3.1. I'll also try to port it back to earlier branches if the cherrypick is smooth > 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 > Priority: Major > Fix For: 3.0.1, 3.2.0 > > > 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 short-term fix it by disabling > validateCooperationAssignment for built-in cooperativeStickyAssignor because > we've already consider the generation in the assignor, and discard the old > generation ownedPartition if any. -- This message was sent by Atlassian Jira (v8.20.1#820001)
