@fhueske Thank you for your reply. Yes, I am always on the newest master
branch every time I write code. What you said about causes that issue reason,
it is did defined in ```org.apache.flink.table.utils._```. **But** the error is
that ```UserDefinedFunctionTestUtils``` imports twice in the same scope. If we
drop ```_``` and import specific class, we can get rid of this error. In
```import org.apache.flink.table.utils._``` package, there is a class called
```UserDefinedFunctionTestUtils``` and aslo in
```org.apache.flink.table.runtime.utils```, there is an object called
```UserDefinedFunctionTestUtils```. So, that is directly leading to the
compiler can not distinguish which one we want to choose.
BTW, I dont down what the reaction to this on Linux or Mac. I can not
afford a Mac, so I think i can found this error. Lol.
Yes. Recenly, I also found it seems that we have a new review code way like
#4444 . OKay. I will follow the rule next time opening a PR.
Thanks again,
Minglei.
