Reporter: Rob Vesse
Fix For: 1.1.0

If you try and run Giraph compiled for YARN but have not specified any external
Zookeeper settings in your Hadoop configuration files you'll receive the
following error:
Exception in thread "main" java.lang.NullPointerException

This looks to be a trivial fix for which I will attach a proposed patch
