> Currently Pig Latin support following LOAD syntax:
> {code}
> LOAD 'data' [USING loader function] [AS schema];      
> {code}
> where data is the name of the file or directory, including files specified with Hadoop-supported
globing syntax. This name is passed to the loader function.
> This feature is to support loaders that can load multiple files from different directories
and allows users to pass in the file names in a comma separated string.
> For example, these will be valid load statements:
> {code}
> LOAD '/usr/pig/test1/a,/usr/pig/test2/b' USING someloader()';
> {code}
> and 
> {code}
> LOAD '/usr/pig/test1/{a,c},/usr/pig/test2/b' USING someloader();
> {code}
> This comma separated string is passed to the loader.
