>             Project: Pig

>            Reporter: Richard Ding

> When a file is assigned to multiple mappers (one block per mapper), the 
> blocks may not end at the exact record boundary. Special care is taken to 
> ensure that all records are loaded by mappers (and exactly once), even for 
> records that cross the block boundary. 
> The PigStorage, however, doesn't correctly handle the case where a block ends 
> at exactly record boundary and results in missing records.
