------------------------------------

             Summary: UDF cannot be in the join condition in blink planner
                 Key: FLINK-14547
                 URL: https://issues.apache.org/jira/browse/FLINK-14547
             Project: Flink
          Issue Type: Bug
          Components: Table SQL / Planner
    Affects Versions: 1.9.1, 1.9.0
            Reporter: Huang Xingbo


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
