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