[jira] [Created] (KAFKA-20271) Initialize assignment epoch to -1 when there is no assignment yet

Sean Quah created KAFKA-20271:
---------------------------------

             Summary: Initialize assignment epoch to -1 when there is no assignment yet
                 Key: KAFKA-20271
                 URL: https://issues.apache.org/jira/browse/KAFKA-20271
             Project: Kafka
          Issue Type: Sub-task
          Components: group-coordinator
            Reporter: Sean Quah


When creating a group, the assignment epoch is initialized to 0.
When tombstoning a group, the assignment epoch is set to -1.

Look into whether we can use -1 for both.

Some tests fail when initializing the assignment epoch to -1:
 * DescribeGroup tests fail because the assignment epoch is -1 instead of 0.
 * ConsumerGroup state tests fail because the consumer group enters ASSIGNING because the group epoch (0) is greater than the assignment epoch (-1).
