Allow multiple paths in the load statement
------------------------------------------
Key: PIG-252
URL: https://issues.apache.org/jira/browse/PIG-252
Project: Pig
Issue Type: Improvement
Reporter: Olga Natkovich
>From Tom White:
I;m having a problem loading data from multiple paths in Pig. What I'm trying
to do is to load data from a range of dates, so I would like to specify an
input of two globbed paths:
x = LOAD '2008/05/{26,27,28,29,30,31},2008/06/{1,2}'
Pig doesn't seem to like this though as it's trying to interpret it as a single
path. The best I can do it to use UNION:
x1 = LOAD '2008/05/{26,27,28,29,30,31}'
x2 = LOAD '2008/06/{1,2}'
x = UNION x1, x2
The downside to this is that I want to parameterize my paths, and having
separate script for each number of paths in the input is cumbersome.
Is there a better way of doing this? Are there any plans to support multiple
paths, and/or PathFilters?
