----------------------------------
Just for reference, to disable all optimizations, use:
{code}
set pig.optimizer.rules.disabled 'all';
{code}
> disable optimizations via pig properties

> Reporter: Travis Crawford
> Assignee: Travis Crawford

>
> Pig provides a number of optimizations which are described at
> [http://pig.apache.org/docs/r0.11.1/perf.html#optimization-rules]. As is
> described in the docs, all or specific optimizations can be disabled via the
> command-line.
> Currently the caller of a pig script must know which optimizations to disable
> when running because that information cannot be set in the script itself. Nor
> can optimizations be disabled site-wide through pig.properties.
> Pig should allow disabling optimizations via properties so that pig scripts
> themselves can disable optimizations as needed, rather than the caller
> needing to know what optimizations to disable on the command-line.
