SYMPTOM: Attempting to submit a Pig job via WebHCat that defines parameter(s) for substitution as command-line arguments results in an "incorrect usage" message and job does not run. Doing the same through Hue results in an "undefined parameter" message and job does not run.
ROOT CAUSE: If the parameter is passed to curl as a single argument (-d 'arg=-param paramName=paramValue') it is interpreted incorrectly by Pig. Submitting the parameter via Hue as a single argument has the same unwanted effect.
