> 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.
