java.lang.AssertionError in o.a.g.a.m.TestDataFileAvroStoreMapReduce [WAS Re: null.pointer.Exception in o.a.g.util.IOUtils]

Hi Ioannis,

This is excellent, I've built locally and can confirm your commit
solves the tests in question.

There are still 2 failing tests within this module [1], namely
testCountQuery and testWordCount. These look more like a bug or typo
somewhere in the code. I've not had much time to look into them yet.
What's promising is that, again, both stack traces are identical :0)

I've kicked off a build on Jenkins to run through after your commit so
we will see if this has positive implications elsewhere... fingers
crossed.
