------------------------------------

             Summary: CompositeInputFormat in Hama
                 Key: HAMA-774
                 URL: https://issues.apache.org/jira/browse/HAMA-774
             Project: Hama
          Issue Type: New Feature
          Components: bsp core
    Affects Versions: 0.6.2
            Reporter: Martin Illecker
            Assignee: Martin Illecker
            Priority: Minor
             Fix For: 0.6.3


*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}
