Dmitriy V. Ryaboy commented on PIG-2903:
----------------------------------------

Can you post the script you are passing this to? If the parameter value is not being used in quotes inside the script, that makes absolute sense (you probably want to pass "''" as the value, instead). If the parameter value _is_ being used in quotes, this is a bug.
