I should have been more clear, the idea was to document **if you specify a
Maven command** you can pass -T 1C to that Maven command, but I like what you
tried and think this is how it should be implemented so I'm adding this feature
and testing with:
dev/make-distribution.sh --name hadoop-2.7.0 -T 1C -Psparkr -Pyarn
-Phadoop-2.7 -Phive -Phive-thriftserver -Dscala-2.11
Will update my pull request shortly, almost done
