Hong Tang commented on PIG-652:
-------------------------------

Since this API is supposed to provide backend specific output classes, 
shouldn't the API take a parameter describing the backend?

For MR backend, the returned class would be implementing OutputFormat<Text, 
Tuple> ? Also, need to make it public the keys in the JobConf object describing 
path, schema, compression, etc.

> Need to give user control of OutputFormat

> Pig currently allows users some control over InputFormat via the Slicer and 
> Slice interfaces.  It does not allow any control over OutputFormat and 
> RecordWriter interfaces.  It just allows the user to implement a storage 
> function that controls how the data is serialized.  For hadoop tables, we 
> will need to allow custom OutputFormats that prepare output information and 
> objects needed by a Table store function.
