> Under the following conditions, a NullPointerException is caused when
> PigStorage is used:
> If in the script, only the 2nd and 3rd column of the data (say) are used, the
> PruneColumns optimization passes this information to PigStorage through the
> pushProjection() method. If the data contains a row with only one column
> (malformed data due to missing cols in certain rows), PigStorage returns a
> Tuple backed by a null ArrayList. Subsequent projection operations on this
> tuple result in the NPE.
