Github user clarkyzl commented on the issue: https://github.com/apache/flink/pull/3407 Hi @KurtYoung . Thanks for your reviewing. I've pushed another commit. This patch is based on https://github.com/apache/flink/pull/3389. If we can get https://github.com/apache/flink/pull/3389 merged first, this patch will look simpler. @twalthr , could you please take a look at https://github.com/apache/flink/pull/3389 ? Thank you all so much.
