Jonathan Coveney created PIG-3088:
-------------------------------------
Summary: Add a builtin udf which removes prefixes
Key: PIG-3088
URL: https://issues.apache.org/jira/browse/PIG-3088
Project: Pig
Issue Type: New Feature
Reporter: Jonathan Coveney
Assignee: Jonathan Coveney
This is something that I always hear people complaining about. Note that this
depends on the FlattenOutput annotation.
This UDF supports the following.
{code}
a = load 'a' as (x1, y1, z1);
b = load 'a' as (x2, y2, z2);
c = join a by x1, b by x2;
describe c;
--c: {a::x1: bytearray,a::y1: bytearray,a::z1: bytearray,b::x2:
bytearray,b::y2: bytearray,b::z2: bytearray}
d = foreach c generate RemovePrefix(*);
describe d;
--d: {x1: bytearray,y1: bytearray,z1: bytearray,x2: bytearray,y2: bytearray,z2:
bytearray}
{code}
