---------------------------------------
[~kkonstantine] thanks for the great summary!
> MockConsumer#endOffsets should be idempotent

> Key: KAFKA-9686
> URL: https://issues.apache.org/jira/browse/KAFKA-9686
> Project: Kafka
> Issue Type: Bug
> Reporter: Chia-Ping Tsai
> Assignee: Chia-Ping Tsai
> Priority: Major
>
> {code:java}
> private Long getEndOffset(List<Long> offsets) {
> if (offsets == null || offsets.isEmpty()) {
> return null;
> }
> return offsets.size() > 1 ? offsets.remove(0) : offsets.get(0);
> }
> {code}
> The above code has two issues.
> 1. It does not return the latest offset since the latest offset is at the end
> of offsets
> 1. It removes the element from offsets so MockConsumer#endOffsets gets
> non-idempotent
