Description

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

 
job.setInputFormat(CompositeInputFormat.class);
job.set("bsp.join.expr", CompositeInputFormat.compose("inner",
   SequenceFileInputFormat.class, aPath, bPath));
