Hi @davies and @tdas , I met a problem of converting Python `int` into Java
`Long`, the Java API in KafkaUtils requires offset as `Long` type, this is
simple for Python 2, since Python 2 has a built-in `long` type which can be
mapped to Java `Long` through py4j automatically, but python 3 only has `int`
type, and py4j will map python `int` into Java `Integer`, I'm not sure how to
support `Long` in python 3.
A simple solution is to modify all the Java-Python interface to change to
type `Interger`, but it may not support super large offset. I'm not sure is
there any other solution. Sorry for dumb question and thanks a lot in advance.
