    Hi @zhangminglei, are you sure that this is not an issue with your local 
setup?
    In the master branch, there is only one class 
`UserDefinedFunctionTestUtils` in org.apache.flink.table.runtime.utils`. It was 
previously located in `org.apache.flink.table.utils._` (and still is in the 
`release-1.3` branch) but was recently moved to the new location. Maybe 
something went wrong when you updated or switched your branch.
    
    Can you clone a new copy of the master branch and try to build it?
    I'm not opposed to the change you are proposing. I'd just like to 
understand the cause of the problem.
    
    Thanks, Fabian
