hadoop-common:test-jar pulls in:

http://central.maven.org/maven2/org/apache/hadoop/hadoop-annotations/2.6.0/hadoop-annotations-2.6.0.pom

With two different profiles, the os.linux profile activates for me as
well, as the activation here is "Not a mac".

The newer Hadoop 2.7.1 seems to have fixed to these activations.

http://central.maven.org/maven2/org/apache/hadoop/hadoop-annotations/2.7.1/hadoop-annotations-2.7.1.pom

(Hadoop 2.7 presumably no longer works on JDK6)


We don't need the tools.jar for our test, so while upgrading to 2.7.1 would fix this - it would also mean we could no longer support JDK6. So I suggest adding an <exclusion> on tools.jar on our hadoop test dependency.
