      Description

      StreamInputFormat doesn't 'seek' to the right offset for the split, therefore leading to a situation where every map reads the same input-split and processes it; also the StreamLineRecordReader has a bug where it doesn't clear out the contents of previous keys/values and that data is appended to each subsequent key/value.
