I have a legacy dataset that has its own unique representation null '\N'. I'd like to use the existing PigStorage loader functionality, but slightly adjust how it reads data. I would like to create a new LoadStoreCaster that would handle my special null value representation. I'd like to add another arg to PigStorage that would allow the end user to specify the name of the LoadStoreCaster class used to perform type conversions, with Utf8StorageConverter being the default value if nothing is specified.
Would such a change make sense? Thanks, Saj
