Ewen Cheslack-Postava commented on KAFKA-3006:
----------------------------------------------
[~gwenshap] I double checked because of [~jkreps]'s comment and that's not
*exactly* the situation -- at least some frameworks (e.g. Storm) seem to leave
the dependency as {{provided}} rather than including the required version in
their packages. So while I agree the actual stream processing application won't
be impacted directly, it could cause some mismatch pain for folks responsible
for deploying it. On the other hand, maybe it's not that big a deal since you
already would have to be careful to deploy the right version to use the new
consumer anyway?

> Key: KAFKA-3006
> URL: https://issues.apache.org/jira/browse/KAFKA-3006
> Project: Kafka
> Issue Type: Improvement
> Components: clients
> Affects Versions: 0.9.0.0
> Reporter: Pierre-Yves Ritschard
> Labels: patch
>
> The KafkaConsumer API has some annoying inconsistencies in the usage of
> collection types. For example, subscribe() takes a list, but subscription()
> returns a set. Similarly for assign() and assignment(). We also have pause()
> , seekToBeginning(), seekToEnd(), and resume() which annoyingly use a
> variable argument array, which means you have to copy the result of
> assignment() to an array if you want to pause all assigned partitions. We can
> solve these issues by adding the following variants:
> {code}
> void subscribe(Collection<String> topics);
> void subscribe(Collection<String> topics, ConsumerRebalanceListener);
> void assign(Collection<TopicPartition> partitions);
> void pause(Collection<TopicPartition> partitions);
> void resume(Collection<TopicPartition> partitions);
> void seekToBeginning(Collection<TopicPartition>);
> void seekToEnd(Collection<TopicPartition>);
> {code}
> This issues supersedes KAFKA-2991
