> For the purposes of tracing usage and statistics of Pig scripts, I'd like to
> be able to correlate the information PPNL can now collect with the script
> that was actually running. Currently, a script id gets passed into every PPNL
> call, but it's just a UUID, so one can't compare it to other executions of
> the same script.
> It seems to me like most of what I need would be taken care of by adding a
> setScriptPlan(String lp) method to the PPNL interface, and calling it from
> ScriptState's setScriptFeatures(LogicalPlan lp). My PPNL could then walk the
> plan and come up with some representation that would be reusable between
> different runs of the same script.
> This would be a backwards incompatible change, as it requires adding a method
> to an interface. PPNL is labeled as evolving, and I don't believe that it's
> widely used at the moment.
