dujian0068 updated KAFKA-17015:
-------------------------------
    Description: 
when review PR#16970。 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
