accessing external data in Load/Store functions

[Shane Evans]

Hi,

I am writing a storage converter (implementing ReversibleLoadStoreFunc) 
for pig 0.4. The schema for this data is stored in an external file and 
I need this schema to correctly serialize and deserialize the format I 
am working with. I can't see any obvious way to load this external file 
within my storage converter.

I can see that I have a reference to the DataStorage and ExecType in the 
determineSchema method and I can call FileLocalizer.open(..), but 
determineSchema isn't called when storing data so I don't have a 
reference to a DataStorage or ExecType at any point. I could call the 
FileLocalizer.openDFS(String) method, but I would like my 
StorageConverter to work in local mode. I am new to pig and I feel that 
I must be missing something. Any suggestions are appreciated.

Thanks,

Shane
