> 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.
