[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.
