[jira] [Created] (KAFKA-9989) StreamsUpgradeTest.test_metadata_upgrade could not guarantee all processor gets assigned task

Boyang Chen created KAFKA-9989:
----------------------------------

             Summary: StreamsUpgradeTest.test_metadata_upgrade could not guarantee all processor gets assigned task
                 Key: KAFKA-9989
                 URL: https://issues.apache.org/jira/browse/KAFKA-9989
             Project: Kafka
          Issue Type: Bug
            Reporter: Boyang Chen
            Assignee: Boyang Chen


System test StreamsUpgradeTest.test_metadata_upgrade could fail due to:

"Never saw output 'processed [0-9]* records' on ubuntu@worker6"

which if we take a closer look at, the rebalance happens but has no task assignment. We should fix this problem by making the rebalance result as part of the check, and skip the record processing validation when the assignment is empty.
