----------------------------------

             Summary: 
ContextualRecord#hashCode()、ProcessorRecordContext#hashCode() Should not be 
deprecated and throw an exception
                 Key: KAFKA-17015
                 URL: https://issues.apache.org/jira/browse/KAFKA-17015
             Project: Kafka
          Issue Type: Improvement
            Reporter: dujian0068


when review PR#16416。 I find function 
`ContextualRecord#hashCode()、ProcessorRecordContext#hashCode() ` be deprecated 
because they have a mutable attribute, which will cause the hashCode to change。 

I don't think that hashCode should be discarded just because it is mutable. 
HashCode is a very important property of an object. It just shouldn't be used 
for hash addressing, like ArayList
