             Summary: Use the position of the Kafka Consumer to track progress 
instead of Consumer Records offsets
                 Key: HIVE-20561
                 URL: https://issues.apache.org/jira/browse/HIVE-20561
             Project: Hive
          Issue Type: Bug
    Affects Versions: 4.0.0
            Reporter: slim bouguerra
            Assignee: slim bouguerra
             Fix For: 4.0.0


Kafka Partitions with transactional messages (post 0.11) will include commit or 
abort markers which indicate the result of a transaction. The markers are not 
returned to applications, yet have an offset in the log. Therefore the end of 
Stream position can be the offset of a control message. 
This Patch change the way how we keep track of the consumer position by using  
{code} consumer.position(topicP) {code} as oppose to using the offset of the 
consumed messages.
Also I have done some refactoring to help code readability  hopefully.
