Github user manku-timma commented on the pull request: https://github.com/apache/spark/pull/322#issuecomment-39530349 After looking at the code a bit more, I see that the code to setContextClassLoader does not use SecurityManager AFAIS. createClassLoader is creating a File object. addReplClassLoaderIfNeeded is dynamically loading a class file. I dont see any use of SecurityManager in these two methods. I am not sure if it gets used implicitly.
