[jira] [Created] (KAFKA-15554) Update client state machine to align with protocol sending one assignment at a time

Lianet Magrans created KAFKA-15554:
--------------------------------------

             Summary: Update client state machine to align with protocol sending one assignment at a time 
                 Key: KAFKA-15554
                 URL: https://issues.apache.org/jira/browse/KAFKA-15554
             Project: Kafka
          Issue Type: Sub-task
          Components: clients, consumer
            Reporter: Lianet Magrans
            Assignee: Lianet Magrans


The new consumer group protocol will be sending one assignment to the member, and wait for an ack or timeout before sending any other assignment. 

The client state machine will be updated so that it takes on new target assignment only if there is no other in process. If a new target assignment is received in this case, the member should fail with a fatal error, as this is not expected in the protocol.
