-----------------------------------
Summary: 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: Bug
Reporter: Apurva Mehta
Assignee: Guozhang Wang
Priority: Blocker
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.
