Thanks a lot @cloud-fan for your review. I think the issue still exists,
problem is that unit test actually doesn't reflect this issue, let me change
the unit test.
You could try the below to see the issue.
```
val dataset = Seq(1, 2, 3).toDS
val mappedDataset = dataset.map(_ + 1)
mappedDataset.as("t1").joinWith(mappedDataset.as("t2"), $"t1.value" ===
$"t2.value").show()
```
