Review Comment:
Hi, @1996fanrui nice catch.
sorry for no explaining this change before the review.
When debugging the line, it was caused by `Expect exception mechanism`
difference between junit4 and junit5. to be short, in junit4, the target line
`assertThat(hadoopInputFormat.hasNext, is(true));` was not executed.
So the change occurred to here.
