> Pig return code for dryrun
> --------------------------
>
> Key: PIG-1522
> URL: https://issues.apache.org/jira/browse/PIG-1522
> Project: Pig
> Issue Type: Improvement
> Affects Versions: 0.6.0, 0.7.0
> Reporter: Justin Hu
>
> Pig returns 1 for dryrun with the message:
> "Dry run completed. Substituted pig script is at ..."
> Some users are confused by the code "1", which usually indicate an error of
> the operation. Because the dryrun is completed successfully, users expect
> "0".
> The Pig Error Handling doesn't specify the code for dryrun. It may make
> sense to return "0" for successful dryrun, or explain it in the document.
