--------------------------------
Issue Type: Sub-task (was: Bug)
Parent: KAFKA-4815
> TransactinoCoordinator does not bump epoch when aborting open transactions
> --------------------------------------------------------------------------
>
> Key: KAFKA-5231
> URL: https://issues.apache.org/jira/browse/KAFKA-5231
> Project: Kafka
> Issue Type: Sub-task
> Reporter: Apurva Mehta
> Assignee: Guozhang Wang
> Priority: Blocker
> Labels: exactly-once
> Fix For: 0.11.0.0
>
>
> When the TransactionCoordinator receives an InitPidRequest when there is an
> open transaction for a transactional id, it should first bump the epoch and
> then abort the open transaction.
> Currently, it aborts the open transaction with the existing epoch, hence the
> old producer is never fenced.
