Status: Patch Available (was: Open)
> PigStorage may miss records when loading a file
> -----------------------------------------------

> Key: PIG-1080
> URL: https://issues.apache.org/jira/browse/PIG-1080
> Project: Pig
> Issue Type: Bug
> Reporter: Richard Ding

> Attachments: PIG-1080.patch
>
>
> 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.
