> *Adapting Hadoop CompositeInputFormat to Hama.*
> Adapt the CompositeInputFormat from Hadoop and integrate it into Hama.
> e.g., Useful for matrix multiplication example by doing a inner join of two matrices.
> Therefore the Hadoop join package has been adapted within *org.apache.hama.bsp.join*.
> Finally I would need some help to integrate the CompositeInputFormat into Hama by using
> {code} 
> job.setInputFormat(CompositeInputFormat.class);
> job.set("bsp.join.expr", CompositeInputFormat.compose("inner",
>    SequenceFileInputFormat.class, aPath, bPath));
> {code}
