Jeff Zhang commented on PIG-259:
--------------------------------
Alan,
In the patch I created a PigStorage constructor with a second argument indicate
whether to overwrite. And the reason I change the StoreFuncInterface is that
I'd like the users who want to create customized StoreFunc has the option to
support overwrite.
Besides I need the overwrite information in InputOutputFileVisitor and
JobControlCompiler, But in these two classes I only can get StoreFuncInterface.
One way to work around is to check the class whether it is PigStorage, and then
cast it to PigStorage, but it seems to me not so friendly and extensible.
