Description

I used to be able to debug my Spark apps in Eclipse. With Spark 1.3.1 I created a launch and just set the vm var "-Dspark.master=local[4]".
With 1.4 this stopped working when reading files from the OS filesystem. Running the same apps with spark-submit works fine. Loosing the ability to debug that way has a major impact on the usability of Spark.

The following exception is thrown:
