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

How do I get the schema information from Pig? I thought you would put the 
schema in the JobConf and pass it to the customized OutputFormat class to 
create RecordWriter.

> 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.
