Alan Gates commented on PIG-1717:
---------------------------------
Ideally I would like to pick A, since that is the clean solution. But we don't
want to break this interface in the next release. Given that, I'd say we go
with B and document that in the future when we need to change that interface
anyway we would also like to make this change. Thoughts? Objections?
> pig needs to call setPartitionFilter if schema is null but getPartitionKeys
> is not

> I'm writing a loader that works with hive style partitioning e.g.
> /logs/type1/daydate=2010-11-01
> The loader does not know the schema upfront and this is something that the
> user adds in the script using the AS clause.
> The problem is that this user defined schema is not available to the loader,
> so the loader cannot return any schema, the Loader does know what the
> partition keys are and pig needs in some way to know about these partition
> keys.
> Currently if the schema is null pig never calls the
> LoadMetaData:getPartitionKeys method or the setPartitionFilter method.
