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

             Summary: When selected KeyValueTextInputFormat, workers get only one value for key
                 Key: HAMA-772
                 URL: https://issues.apache.org/jira/browse/HAMA-772
             Project: Hama
          Issue Type: Bug
          Components: bsp core
    Affects Versions: 0.6.2
            Reporter: Ikhtiyor Ahmedov
            Priority: Minor
             Fix For: 0.7.0


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.
