We should set a long session timeout, to be sure that the group ends up empty because the consumer left it intentionally even if interrupted (and not because its session expired and the broker kicked it out). We can override the broker configs with the existing [brokerPropertiesOverrides](https://github.com/apache/kafka/blob/704476885ffb40cd3bf9b8f5c368c01eaee0a737/core/src/test/scala/integration/kafka/api/AbstractConsumerTest.scala#L70), and we should also be careful to do it only for this test (to not affect behaviour in others, like it's done [here](https://github.com/apache/kafka/blob/704476885ffb40cd3bf9b8f5c368c01eaee0a737/core/src/test/scala/integration/kafka/api/BaseAdminIntegrationTest.scala#L202) I believe). -- This is an automated message from the Apache Git Service.
