> Kafka Consumer Config validation should be AND not OR
> -----------------------------------------------------
>
> Key: KAFKA-3533
> URL: https://issues.apache.org/jira/browse/KAFKA-3533
> Project: Kafka
> Issue Type: Bug
> Reporter: Ryan P
> Labels: Newbie
>
> There seems to be a bit of an inconsistency between between the configuration
> validation imposed in the KafkaConsumer class and the error message presented:
> https://github.com/apache/kafka/blob/trunk/clients/src/main/java/org/apache/kafka/clients/consumer/KafkaConsumer.java#L556-L557
> Based on the error message the request timeout should be greater than the
> session timeout and the max fetch wait timeout. The validation logic however
> checks to ensure that either operand is true, not both.
> In the event that your request timeout is greater than the session timeout
> the operation will be short-circuited allowing for a potential
> misconfiguration of the consumer.
> Based on what I can tell the error message is correct and the validation
> check is incorrect.
