When JVM is started in a Python process, it should exit once the stdin is closed. test: add spark.driver.memory in conf/spark-defaults.conf ``` daviesdm:~/work/spark$ cat conf/spark-defaults.conf spark.driver.memory 8g daviesdm:~/work/spark$ bin/pyspark >>> quit daviesdm:~/work/spark$ jps 4931 Jps 286 daviesdm:~/work/spark$ python wc.py 943738 0.719928026199 daviesdm:~/work/spark$ jps 286 4990 Jps ``` Author: Davies Liu <davies@databricks.com> Closes #3274 from davies/exit and squashes the following commits: df0e524 [Davies Liu] address comments ce8599c [Davies Liu] address comments 050651f [Davies Liu] JVM should exit after Python exit
