> This patch adds multiple record writers to allow Hive user writing data directly to a Kafka Topic.
> The end goal is have a writer that provides multiple write semantics modes.
> * A At_most_once where all the records will be delivered with no guarantee or reties eg best effort mode. (Done)
> * B At_least_once, each record will be delivered with retries from the Kafka Producer and Hive Write Task. (Done)
> * C Exactly_once , Writer will be using Kafka Transaction API to ensure that each record is delivered once. (not so, still need more discussions)
> In addition to the new feature i have refactored the existing code to make it more readable.
