Pradeep Kamath commented on PIG-1063:

The 1 javac warning is due to the deprecation warning explained in my previous 
comment. The unit test failure seems unrelated and looks like a temporary env. 
issue - resubmitting to check if the tests pass now.

> Pig does not call checkOutSpecs() on OutputFormat provided by StoreFunc in

>             Project: Pig
>          Issue Type: Bug
>    Affects Versions: 0.4.0

> 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}
