[jira] [Created] (FLINK-25294) Incorrect cloudpickle import

arya created FLINK-25294:
----------------------------

             Summary: Incorrect cloudpickle import
                 Key: FLINK-25294
                 URL: https://issues.apache.org/jira/browse/FLINK-25294
             Project: Flink
          Issue Type: Bug
          Components: API / Python
    Affects Versions: 1.14.0
            Reporter: arya


In flink-python/pyflink/fn_execution/coder_impl_fast.pyx line 30
{code:python}
from cloudpickle import cloudpickle
{code}
should simply be
{code:python}
import cloudpickle{code}
or else I get AttributeError: module 'cloudpickle.cloudpickle' has no attribute 'dumps' when using keyed states

I assume this is left over from when cloudpickle was incorrectly packaged, then fixed in [FLINK-14556|https://issues.apache.org/jira/browse/FLINK-14556], so this might have been a problem since 1.10.0
