 A bit change of the interface of Tuple  DataBag ( make the set and append 
 method return this)

 Key: PIG-1166
 URL: https://issues.apache.org/jira/browse/PIG-1166
 Project: Pig
  Issue Type: Improvement
Reporter: Jeff Zhang
Assignee: Jeff Zhang
Priority: Minor
 Attachments: Pig_1166.patch


 When people write unit test for UDF, they always need to build a tuple or 
 bag. If we change the interface of Tuple and DataBag,  make the set and 
 append method return this, it can decrease the code size.  e.g. Now people 
 have to write the following code to build a Tuple:
 {code}
 Tuple tuple=TupleFactory.getInstance().newTuple(3);
 tuple.set(0,item_0);
 tuple.set(1,item_1);
 tuple.set(2,item_2);
 {code}
 If we change the interface,  make the set and append method return this, we 
 can rewrite the above code like this:
 {code}
 Tuple tuple=TupleFactory.getInstance().newTuple(3);
 tuple.set(0,item_0).set(1,item_1).set(2,item_2);
 {code}
 This interface change won't have back compatibility problem and I think 
 there's no performance problem too.
