Xingcan Cui commented on FLINK-7764:
------------------------------------
This problem may be caused by the recent refactoring of Kafka producers.
The {{FlinkKafkaProducer010Configuration}} returned by
{{writeToKafkaWithTimestamps()}} (the {{producer}} in description) is a
{{DataStreamSink}} itself. However, another {{DataStreamSink}} has already been
generated when adding the {{KafkaProducer}} as the sink in
{{writeToKafkaWithTimestamps()}}. Thus manipulating the returned configuration
object (e.g., {{producer.name("foo")}}) will not affect the worked
{{Transformation}} in the existing {{DataStreamSink}} (i.e.,
{{originalSink.getTransformation()}}).
Since it's hard to change the internal construction logic of a job, to solve
this, maybe we can only override all the {{DataStreamSink}} public methods in
{{FlinkKafkaProducer010Configuration}} to work on the existing
{{Transformation}}.
What do you think [~fhueske]?

> When I try to use KafkaProducer with timestamps it fails to set name, uid or
