Cheolsoo Park commented on PIG-4511: ------------------------------------ +1. I'll commit the patch soon. > Add columns to prune from PluckTuple > ------------------------------------ > > Key: PIG-4511 > URL: https://issues.apache.org/jira/browse/PIG-4511 > Project: Pig > Issue Type: Improvement > Affects Versions: 0.14.0 > Reporter: Joseph Babcock > Assignee: Joseph Babcock > Priority: Minor > Fix For: 0.15.0 > > Attachments: pluckTuple.patch > > > Currently pluckTuple returns all columns in relation that match a prefix > predicate. This patch allows a boolean flag 'false' to specify that columns > NOT matching this prefix should be retained. > Example: > <source> > a = load 'a' as (x:int,y:chararray,z:long) > b = load 'b' as (x:int,y:chararray,z:long) > c = join a by x, b by x; > Define pluck PluckTuple('a::','false') > -- returns b > </source> -- This message was sent by Atlassian JIRA (v6.3.4#6332)
