Allen Wittenauer commented on HDFS-3296:
----------------------------------------

bq. The patch here won't help with any compilation problems. 

Correct.  I'm well past that point and now trying to get unit tests to work.  native unit tests are failing in hadoop-common because they can't find libhadoop.so.  I ended up writing pretty much the exact same change to hadoop-project/pom.xml (since replaced with what you have here) and am manually patching the pom prior to launching maven on the build host.  We're now left with a bunch of other problems, including this likely related one:

(from https://builds.apache.org/view/H-L/view/Hadoop/job/hadoop-trunk-osx-java8/14/console )

I think I'm going to set up a precommit job for Mac so that folks can manually trigger it to test Mac-specific patches.

bq. target the Mac OS X 10.10 SDK

The Mac mini in the build infrastructure is a 10.9 box.
