Kirk True updated KAFKA-18873: ------------------------------ Component/s: producer > Incorrect error message for max.in.flight.requests.per.connection when using > transactional producer. > ---------------------------------------------------------------------------------------------------- > > Key: KAFKA-18873 > URL: https://issues.apache.org/jira/browse/KAFKA-18873 > Project: Kafka > Issue Type: Bug > Components: clients, producer > Reporter: Eslam Mohamed > Assignee: Eslam Mohamed > Priority: Minor > Original Estimate: 1h > Remaining Estimate: 1h > > > {code:java} > KafkaProducerTest.testInflightRequestsAndIdempotenceForIdempotentProduces{code} > {{Above unit test }}checks for configuration validation errors when > instantiating a {{ProducerConfig}} with invalid properties. One of the > assertions in this test "invalidProps4" is designed to validate the > constraint that {{max.in.flight.requests.per.connection}} must be at most > {{5}} when using a transactional producer. However, the error message thrown > by the {{ProducerConfig}} constructor in this scenario is incorrect. > * *Observed Behavior:* > When {{max.in.flight.requests.per.connection}} is set to {{6}} for a > transactional producer, the test expects an exception with the message: > {{"Must set max.in.flight.requests.per.connection to at most 5 when using the > transactional producer."}} > Instead, the error message states: > {{"Must set retries to non-zero when using the idempotent producer."}} > * *Expected Behavior:* > The error message should explicitly indicate the violation of the > {{max.in.flight.requests.per.connection}} constraint for transactional > producers: > {{"Must set max.in.flight.requests.per.connection to at most 5 when using the > transactional producer."}} > The mismatch in the error message can lead to confusion for developers > debugging the configuration error, as it incorrectly hints at a {{retries}} > configuration issue instead of the actual > {{max.in.flight.requests.per.connection}} issue. -- This message was sent by Atlassian Jira (v8.20.10#820010)
