Step 1) Install dependencies for yarn
See http://svn.apache.org/repos/asf/hadoop/common/branches/MR-279/mapreduce/yarn/README
See http://svn.apache.org/repos/asf/hadoop/common/trunk/hadoop-mapreduce/hadoop-yarn/README
Make sure protbuf library is in your library path or set: export LD_LIBRARY_PATH=/usr/local/lib
Step 2) Checkout
