[jira] [Created] (KAFKA-16261) MembershipManagerImpl.updateSubscription fails if already empty subscription

Andrew Schofield created KAFKA-16261:
----------------------------------------

             Summary: 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
            Reporter: Andrew Schofield
            Assignee: Lianet Magrans


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.
