Review Comment:
-- Maybe introduce a new constant
ContinuousFileMonitoringFunction.MAX_PARALLELISM = 1
Maybe
[SingleOutputStreamOperator#forceNonParallel](https://github.com/apache/flink/blob/master/flink-streaming-java/src/main/java/org/apache/flink/streaming/api/datastream/SingleOutputStreamOperator.java#L206)
is more appropriate.
-- I also think it would be good to add a comment explaining why this is
necessary.
Done.
