> Project: Kafka
> Issue Type: Bug
> Components: KafkaConnect
> Affects Versions: 0.10.0.0
> Reporter: Jason Gustafson

> Fix For: 0.10.0.1
>
>
> We use consumer.wakeup() to interrupt long polls when we need to pause/resume
> partitions and when we shutdown sink tasks. The resulting {{WakeupException}}
> could be raised from the synchronous commit which we use in between
> rebalances and on shutdown. Since we don't currently catch this exception, we
> can fail to commit offsets, which typically results in duplicates. To fix
> this problem, we should catch the exception, retry the commit, and then
> rethrow it.
