--------------------------------------

             Summary: BatchExecutionKeyedStateBackend is using incorrect ExecutionConfig when creating serializer
                 Key: FLINK-29645
                 URL: https://issues.apache.org/jira/browse/FLINK-29645
             Project: Flink
          Issue Type: Bug
          Components: Runtime / State Backends
    Affects Versions: 1.14.6, 1.15.2, 1.13.6, 1.12.7, 1.16.0, 1.17.0
            Reporter: Piotr Nowojski


{{org.apache.flink.streaming.api.operators.sorted.state.BatchExecutionKeyedStateBackend#getOrCreateKeyedState}} is using freshly constructed {{ExecutionConfig}}, instead of the one configured by the user from the environment.


{code:java}
    public <N, S extends State, T> S getOrCreateKeyedState(
            TypeSerializer<N> namespaceSerializer, StateDescriptor<S, T> stateDescriptor)
            throws Exception {
        checkNotNull(namespaceSerializer, "Namespace serializer");
        checkNotNull(
                keySerializer,
                "State key serializer has not been configured in the config. "
                        + "This operation cannot use partitioned state.");

        if (!stateDescriptor.isSerializerInitialized()) {
            stateDescriptor.initializeSerializerUnlessSet(new ExecutionConfig());
        }
{code}

The correct one could be obtained from {{env.getExecutionConfig()}} in {{org.apache.flink.streaming.api.operators.sorted.state.BatchExecutionStateBackend#createKeyedStateBackend}}
