Luke Chen updated KAFKA-13406:
------------------------------
Description:
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.

generation info in validateCooperationAssignment.
