Schema returned in UDF is not used by Pig
-----------------------------------------
Key: PIG-528
URL: https://issues.apache.org/jira/browse/PIG-528
Project: Pig
Issue Type: Bug
Affects Versions: types_branch
Reporter: Santhosh Srinivasan
Assignee: Santhosh Srinivasan
Fix For: types_branch
Using an identity UDF that returns the input schema as the output schema leads
to schema truncation in Pig.
{code}
grunt> a = load '/tudent_tab.data' as (name, age, gpa);
grunt> b = foreach a generate IdentityFunc(name, age);
grunt> describe b;
b: {name: bytearray}
--It should have been b:{(name: bytearray, age: bytearray)}
{code}
The outputSchema method in IdentityFunc is given below:
{code}
@Override
public Schema outputSchema(Schema input) {
return input;
}
{code}
