Sending parameters to a customer load function

[Walker, Alan]

Hi,

I'm having some challenges with a  load function.  It only seems to work with a 
void constructor.  The Java code has a void constructor and a String 
constructor, much like the SimpleTextLoader example.  Any thoughts on what 
might be going wrong?

    public ShoppingReader() {
        parms = "";
    }

    public ShoppingReader(String tmp) {
        parms = tmp;
    }

grunt> A = LOAD '/user/alanw/*.xml' USING 
com.sabre.pigshop.ShoppingReader('all') AS (x);
2012-04-06 16:04:08,593 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 
2999: Unexpected internal error. could not instantiate 
com.sabre.pigshop.ShoppingReader' with arguments '[all]'

Thanks,
Alan.
