> DataSet#print will print the result on client side, while DataStream#print will print the result on TM. This inconsistency will confuse users. IMHO, we should make the behavior consistency between DataSet and DataStream, I prefer to print the result on client side.  Regarding DataStream#print, we can use DataStreamUtils#collect to print it on client side.
