Hi Eli,
Thanks for the response.
I get this error now -

Hi, see here (from your stack trace):
14/05/07 23:45:42 INFO yarn.GiraphYarnClient: Defaulting per-task heap size to
1024MB.
Exception in thread main java.lang.IllegalStateException: Giraph's estimated
cluster heap 2048MB ask is greater than the current available cluster heap of
0MB. Aborting Job.
You'll need to adjust the min/max heap allocations allowed on your YARN cluster
if possible. Alternately you can alter the defaults set up in the Giraph-Yarn
client code and rebuild Giraph with those set differently.

I have the same issue running giraph built with -Phadoop_yarn
-Dhadoop.version=2.2.0 on Hortonworks.
I get classnotfoundexceptions, looks like the GiraphRunner may not be able to
load the classes correctly while running on Yarn.
So if anybody has had success please share your experience, wondering what I
have been doing wrong.
