------------------------------------
Summary: Unexpected Fatal error InvalidTxnStateException on Kafka
Streams (KIP-890)
Key: KAFKA-19690
URL: https://issues.apache.org/jira/browse/KAFKA-19690
Project: Kafka
Issue Type: Bug
Reporter: Ritika Reddy
Assignee: Ritika Reddy
We are seeing cases where a Kafka Streams (KS) thread stalls for ~20 seconds,
resulting in a visible gap in the logs. During this stall, the broker correctly
aborts the open transaction (triggered by the 10-second transaction timeout).
So far, this is expected behavior. However, when the KS thread resumes, instead
of receiving the expected InvalidProducerEpochException (which we already
handle gracefully as part of transaction abort), the client is instead hit with
an InvalidTxnStateException. KS currently treats this as a fatal error, causing
the application to fail.
