> The test case:

> @Test
> def testFilterUdtfOutputPojo(): Unit = {
> val env = ExecutionEnvironment.getExecutionEnvironment
> val tEnv = TableEnvironment.getTableEnvironment(env)
> val pojoFunc1 = new PojoTableFunc()
> tEnv.registerFunction("pojo1", pojoFunc1)
> val result = CollectionDataSets.getSmall3TupleDataSet(env)
> .toTable(tEnv, 'a, 'b, 'c)
> .join(pojoFunc1('c))
> .where(('age > 0) && ('name !== ""))
> .select('a, 'b, 'c, 'age, 'name)
> val results = result.toDataSet[Row].collect()
> }
> {code}
> It will throw exception:
> {code}
> org.apache.flink.table.codegen.CodeGenException: No input mapping is
