Olga Natkovich updated PIG-908:
-------------------------------
Fix Version/s: 0.8.0
> Need a way to correlate MR jobs with Pig statements
> ---------------------------------------------------
>
> Key: PIG-908
> URL: https://issues.apache.org/jira/browse/PIG-908
> Project: Pig
> Issue Type: Wish
> Reporter: Dmitriy V. Ryaboy
> Assignee: Richard Ding
> Fix For: 0.8.0
>
>
> Complex Pig Scripts often generate many Map-Reduce jobs, especially with the
> recent introduction of multi-store capabilities.
> For example, the first script in the Pig tutorial produces 5 MR jobs.
> There is currently very little support for debugging resulting jobs; if one
> of the MR jobs fails, it is hard to figure out which part of the script it
> was responsible for. Explain plans help, but even with the explain plan, a
> fair amount of effort (and sometimes, experimentation) is required to
> correlate the failing MR job with the corresponding PigLatin statements.
> This ticket is created to discuss approaches to alleviating this problem.
