Github user rtudoran commented on the issue: https://github.com/apache/flink/pull/3607 @sunjincheng121 - Apperently there were many conflicts...most of them were stupid conflicts when git was trying to do the automatic merging. At least in 2 classes the methods you added and the ones i added were put one into the other...instead of one after the other. If you look over the classes you we see that actually there are not so many actual modifications :)
