--------------------------------------
Summary: Transaction completion may block unnecessarily after
abortable error
Key: KAFKA-9287
URL: https://issues.apache.org/jira/browse/KAFKA-9287
Project: Kafka
Issue Type: Bug
Reporter: Jason Gustafson
Assignee: Jason Gustafson
This was discovered while investigating the delay in
`AuthorizerIntegrationTest.testTransactionalProducerTopicAuthorizationExceptionInCommit`
which typically takes 35 seconds rather than 5 seconds like most of these
other tests in this class. There is an edge case on transaction completion if
an AddPartitionsToTxn request fails with an abortable error in which the
producer may be left blocking in `NetworkClient.poll` without failing the
pending commit and without any pending requests. Ultimately the test case was
blocking the full 30s request timeout before failing the transaction.
