Hi Jeff,
For FLINK-15935 [1], I try to think of it as a non blocker. But it's really an important issue. The problem is the class loading order. We want to load the class in the blink-planner.jar, but actually load the class in the flink-planner.jar. First of all, the order of class loading is based on the order of classpath. I just tried, the order of classpath of the folder is depends on the order of file names. -That is to say, our order is OK now: because flink-table-blink_2.11-1.11-SNAPSHOT.jar is before the name order of flink-table_2.11-1.11-snapshot.jar. -But once I change the name of flink-table_2.11-1.11-SNAPSHOT.jar to aflink-table_2.11-1.11-SNAPSHOT.jar, an error will be reported. The order of classpaths should be influenced by the ls of Linux. By default the ls command is listing the files in alphabetical order. [1] IDE seems to have another rule, because it is directly load classes. Not jars. So the possible impact of this problem is: -IDE with two planners to use watermark, which will report an error. -The real production environment, under Linux, will not report errors because of the above reasons.
