             Summary: KafkaConsumer.poll throws IllegalStateException
                 Key: KAFKA-5097
                 URL: https://issues.apache.org/jira/browse/KAFKA-5097
             Project: Kafka
          Issue Type: Bug
            Reporter: Ismael Juma
            Assignee: Eno Thereska
            Priority: Critical
             Fix For: 0.10.2.1


The backport of KAFKA-5075 to 0.10.2 seems to have introduced a regression: If 
a fetch returns more data than `max.poll.records` and there is a rebalance or 
the user changes the assignment/subscription after a `poll` that doesn't return 
all the fetched data, the next call will throw an `IllegalStateException`. More 
discussion in the following PR that includes a fix:

https://github.com/apache/kafka/pull/2876/files#r112413428

This issue caused a Streams system test to fail, see KAFKA-4755.

We should fix the regression before releasing 0.10.2.1.
