| PigRecordReader
A wrapper around the actual RecordReader and loadfunc - this is needed for
two reasons
1) To intercept the initialize call from hadoop and initialize the underlying
actual RecordReader with the right Context object - this is achieved by
looking up the Context corresponding to the input split this Reader is
supposed to process
2) We need to give hadoop consistent key-value types - text and tuple
respectively - so PigRecordReader will call underlying Loader's getNext() to
get the Tuple value - the key is null text since key is not used in input to
map() in Pig.
