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

             Summary: change to MockStreamTask breaks OneInputStreamOperatorTestHarness
                 Key: FLINK-12334
                 URL: https://issues.apache.org/jira/browse/FLINK-12334
             Project: Flink
          Issue Type: Bug
          Components: API / DataStream
    Affects Versions: 1.8.0
            Reporter: Cliff Resnick


The move to the MockStreamTask is created with does not include initialization of an Accumulator Map when using the builder

[https://github.com/apache/flink/blob/e43d55445e7abcadb92460bb4d61e28540f1189d/flink-streaming-java/src/test/java/org/apache/flink/streaming/util/AbstractStreamOperatorTestHarness.java#L198]

This results in with a TestHarness whose context contains an immutable empty map and is breaking tests. The fix is simple, please include an actual map in the builder call.
