Description

Several ComputeSpec test cases failed on my cluster:
ComputeSpec_5 - ComputeSpec_13

These scripts have a ship() part in the define, where the ship includes the script file too, so we add the same file to spark context twice. This is not a problem with Hadoop, but looks like Spark doesn't like adding the same filename twice:

Caused by: java.lang.IllegalArgumentException: requirement failed: File PigStreamingDepend.pl already registered.
