Description

At file core/src/main/scala/org/apache/spark/util/Utils.scala
getSystemProperties function fails when someone passes -D to the jvm and as a result the key passed is "" (empty).
Exception thrown: java.lang.IllegalArgumentException: key can't be empty
Empty keys should be ignored or just passed them without filtering at that level as in previous versions.
