[jira] [Created] (FLINK-19892) Replace __metaclass__ field with metaclass keyword

Huang Xingbo created FLINK-19892:
------------------------------------

             Summary: Replace __metaclass__ field with metaclass keyword
                 Key: FLINK-19892
                 URL: https://issues.apache.org/jira/browse/FLINK-19892
             Project: Flink
          Issue Type: New Feature
          Components: API / Python
            Reporter: Huang Xingbo


__metaclass__ is not compatible in some scenarios of python3 e.g.

 
{code:java}
>>> from pyflink.serializers import Serializer
>>> import inspect
>>> inspect.isabstract(Serializer)
False{code}
 

We can replace __metaclass__ field with [metaclass|https://www.python.org/dev/peps/pep-3115/] keyword to solve these problem.
