There is one issue which I would like to bring to your knowledge in MRUNIT. The Datatype 'Pair' return (key + ", " + value) in its toString() method. However this will not be desired format in all cases. Some cases we just need to have (key,value) instead of (key, value) Notice the space between , and value. Should we provide feature to set such separators, rather than hardcoding it.
