Jark Wu closed FLINK-17139.
---------------------------
Resolution: Not A Problem
Hi [~hackergin], [~wenlong.lwl] is correct. This is an expected behavior.
StreamTableEnvironemnt can't reuse sub trees, you can use TableEnvironment
which supports reusing.
Btw, in the upcoming 1.11, both StreamTableEnvironemnt and TableEnvironment
support reusing.
Close this issue because not a problem.
