Kirk True updated KAFKA-16261:
------------------------------
Component/s: consumer
> MembershipManagerImpl.updateSubscription fails if already empty subscription
> ----------------------------------------------------------------------------
>
> Key: KAFKA-16261
> URL: https://issues.apache.org/jira/browse/KAFKA-16261
> Project: Kafka
> Issue Type: Bug
> Components: clients, consumer
> Reporter: Andrew Schofield
> Assignee: Lianet Magrans
> Priority: Minor
> Labels: consumer-threading-refactor, kip-848-client-support
> Fix For: 3.8.0
>
>
> The internal SubscriptionState object keeps track of whether the assignment
> is user-assigned, or auto-assigned. If there are no assigned partitions, the
> assignment resets to NONE. If you call SubscriptionState.assignFromSubscribed
> in this state it fails.
> The easiest thing is perhaps to check
> SubscriptionState.hasAutoAssignedPartitions() to make sure that
> assignFromSubscribed is going to be permitted.
