Edward J. Yoon commented on HAMA-772:
-------------------------------------

It would be nice if you included a unit test. 

And, build fails as below:

{code}

> When KeyValueTextInputFormat selected as job input format, worker tasks are getting only one value for given key.
> Reason: In PartitioningRunner class for collecting data into memory used Map<Integer, Map<Writable, Writable>>, where Integer for worker id, Map is for key/values, if multiple values for same key, all values will be overwritten by the last value.
