Richard Ding updated PIG-1090:
------------------------------

    Attachment: PIG-1090-3.patch

This patch deals with conversions between Pig Schema and the new Resource 
Schema.

Given a resource schema, one calls the folllowing static method of Schema to 
convert it to a Pig schema:

{code}
public static Schema getPigSchema(ResourceSchema rSchema) throws 
FrontendException;
{code}

One the other hand, a Pig schema is converted to a Resource Schema by passing 
it to a resource schema constructor:

{code}
public ResourceSchema(Schema pigSchema) ;
{code}
 
One restriction for Resource Schema is that a Bag defined by Resource Schema 
must contain exactly one field of type Tuple. Ohterwise an exception will 
thrown during the conversion.

Here are results from a local 'test-patch' run:
