Question about flink batch python api's print

Hello,guys.
I use python print in flink map function to see whether i get the data,but
i didn't see anything in client or path log/***.out,just Program execution
finished.
Is there any way to solve this and see print?
Besides,I try to use raise Exception in Map() and flink still complete as
finished!!!Is it a bug?Can flink catch python's error message?
