> A StoreFunc implementation can inform pig of an OutputFormat it uses through
> the getStoragePreparationClass() method. In a query with multiple stores
> which gets optimized into a single mapred job, Pig does not call the
> checkOutputSpecs() method on the outputformat. An example of such a script is:
> {noformat}
> a = load 'input.txt';
> b = filter a by $0 < 10;
> store b into 'output1' using StoreWithOutputFormat();
> c = group a by $0;
> d = foreach c generate group, COUNT(a.$0);
> store d into 'output2' using StoreWithOutputFormat();
> {noformat}
