This got me a build that at least attempts to start to run but not I see the
following:

mbp-rvesse:hadoop-2.2.0 rvesse$ bin/hadoop jar

Which indirectly implies that I have some missing configuration to run
Giraph on YARN.  I don't think that should be a NPE and it looks to be a
trivial fix so I'll try and fix and send a pull request for that.

The error message I should receive if the NPE wasn't happening is the
following:

Giraph on YARN does not currentlysupport Giraph-managed ZK instances: use a
standalone ZooKeeper.

What configuration options do I need to have set to point Giraph at an
external Zookeeper?

Cheers,

Rob
