Hey @andrewor14 , it seems that using security manager may cause a
performance impact as https://issues.apache.org/jira/browse/SPARK-4584 said.
So I tested it(using javaWordCount). They were almost the same and then
using a bigger dataset to test. And same again: with security use 167 second by
average and without it use 166seconds by average. So I doubt security manager
will actually affect the performance of jvm?
