Andrei Yu commented on KAFKA-13406:
-----------------------------------

[~showuon]since the possible fix is in the 
{code:java}
internals/ConsumerCoordinator
{code}
and not in publicly accessible  API of CooperativeStickyAssignor and 
AbstractStickyAssignor which we can pull and customly change and then use 
{code:java}
partition.assignment.strategy
{code} 
mapping to changed class , it's becoming a bit complicated to test on the same 
environment I did before.
Is there any chance to test changes in CooperativeStickyAssignor or 
AbstractStickyAssignor and then port them in internals ?

> 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.
