> 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 wait for the finalized assignment (non-empty) before
> kicking off the record processing validation.
