Subject [jira] [Created] (PIG-3317) disable optimizations via pig properties
Date Thu, 09 May 2013 20:55:16 GMT
Travis Crawford created PIG-3317:

             Summary: disable optimizations via pig properties
                 Key: PIG-3317
                 URL: https://issues.apache.org/jira/browse/PIG-3317
             Project: Pig
          Issue Type: Improvement
            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.
