@fhueske , yes, i just remove the method in `FlinkRelNode` as java
interface only allow public method, just forgot to change the methods in
implemented FlinkRelNode classes.
@twalthr , I'm not sure about what is exactly required in
`TranslationContext`, i would merge this PR soon, then you can update the
`translateToPlan()` on your requirement.
