> 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.
