> Currently, UDF cannot be in the join condition in blink planner, for the
> following example:
> val util = batchTestUtil()
> val left = util.addTableSource[(Int, Int, String)]("Table3",'a, 'b, 'c)
> val right = util.addTableSource[(Int, Int, Int, String, Long)]("Table5", 'd,
> 'e, 'f, 'g, 'h)
> util.addFunction("Func", Func0)
> val result = left
> .leftOuterJoin(right, "a === d && Func(a) === a + d")
> .select("a, d")
> util.verifyExplain(result)
> The following exception will be thrown:
> java.util.NoSuchElementException: No value
> presentjava.util.NoSuchElementException: No value present
