Olga Natkovich commented on PIG-777:

Looks like the patch does more than just log message. I think you need to add a 
unit test for why this is needed:


> Code refactoring: Create optimization out of store/load post processing code
> ----------------------------------------------------------------------------
>                 Key: PIG-777
>                 URL: https://issues.apache.org/jira/browse/PIG-777
>             Project: Pig
>          Issue Type: Improvement
>            Reporter: Gunther Hagleitner
>         Attachments: log_message.patch
> The postProcessing method in the pig server checks whether a logical graph 
> contains stores to and loads from the same location. If so, it will either 
> connect the store and load, or optimize by throwing out the load and 
> connecting the store predecessor with the successor of the load.
> Ideally the introduction of the store and load connection should happen in 
> the query compiler, while the optimization should then happen in an separate 
> optimizer step as part of the optimizer framework.
