Using gora-hbase on AWS EMR

[Adhish Singla]

Hi all,

I am trying to use Gora-HBase for I/O with Giraph-Gora on AWS EMR and this is 
the error I get :

org.apache.giraph.yarn.GiraphYarnTask  - GiraphYarnTask threw a top-level 
exception, failing task

This is probably because jdom is a dependency for gora-hbase and it is not 
included in the gora-hbase.jar .

So is there a way to build gora-hbase with all its dependencies?

Thanks in advance.
