Fix line end character stripping for Windows

LogQuery Spark example would produce unwanted result when run on Windows platform because of different, platform specific trailing line end characters (not only \n but \r too).

This fix makes use of Scala's standard library string functions to properly strip all trailing line end characters, letting Scala handle the platform specific stuff.

spark on yarn - yarn-client mode doesn't always exit immediately

https://spark-project.atlassian.net/browse/SPARK-1049

If you run in the yarn-client mode but you don't get all the workers you requested right away and then you exit your application, the application master stays around until it gets the number of workers you initially requested. This is a waste of resources.  The AM should exit immediately upon the client going away.

This fix simply checks to see if the driver closed while its waiting for the initial # of workers.
