------------------------------------------------------------

Hi, everyone. I have implemented  
*\\{Stream\}ExecutionEnvironment::registerUserJarFile()* interfaces both for 
java and scala API, and they are tested well. Do you think it is better to 
split this task FLINK-14055 into two goals, one for DDL and the other for 
*registerUserJarFile()* interface? I see that there are some use cases in which 
people want to implement their own SQL application based on loading external 
jars for now.

And I'd like to help here and could you please assign the latter goal to me so 
that I can propose a PR on Github as soon as possible?
