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)


Could you try changing all the Hadoop 2.6.0 dependencies in pom.xml to
2.7.1 and see if JDK9 is happy then?

(We can always exclude it tools.jar in the test dependency, I don't
see how it's needed for our tests)
