> GetOffsetShell is implemented on old SimpleConsumer. It needs Zookeeper to retrieve metadata about topics and partitions. At present, GetOffsetShell does the following:
> - get metadata from Zookeeper
> - iterate over partitions
> - for each partition, connect to its leader broker and request offsets
> Instead, GetOffsetShell can use new KafkaConsumer and retrieve offsets by means of endOffsets(), beginningOffsets() and offsetsForTimes() methods. One request is sufficient for all topics and partitions.
> As far as GetOffsetShell is re-implemented with new KafkaConsumer API, it will not depend on obsolete API: SimpleConsumer, old producer API.
