@zjffdu If you take a look
https://github.com/apache/zeppelin/blob/master/notebook/2A94M5J1Z/note.json#L89,
you'll see there're two new lines between outputs. Spark interpreter (scala)
seems printing one more new line between outputs.
Current master displays those new lines correctly. 0.6.x didn't displayed
those new line well.
So, i think one more new line between output in scala is problem need be
addressed in SparkInterpreter in separate issue, while this PR addresses
difference between streaming output and static output.
