Boolean pig UDF constructor
Hi All,

Can I pass in a boolean value to Pig UDF constructor with Pig 0.9.2?

I have a constructor :

 public GenStartEndDate(boolean mtdNoGlob) {

        this.mtdNoGlob = mtdNoGlob;

    }
I am instantiating it in my Pig script :
DEFINE START_END_DATE com.demandmedia.dig.udf.GenStartEndDate(false);
I get :
org.apache.pig.impl.logicalLayer.FrontendException: ERROR 1000: Error
during parsing. <line 4, column 62>  mismatched input 'false' expecting
RIGHT_PAREN
