Merged join/cogroup does not automatically ship loader
------------------------------------------------------
Key: PIG-2030
URL: https://issues.apache.org/jira/browse/PIG-2030
Project: Pig
Issue Type: Bug
Components: impl
Affects Versions: 0.9.0
Reporter: Daniel Dai
Assignee: Daniel Dai
Fix For: 0.9.0
Attachments: PIG-2030-1.patch
The following script fail due to TableLoader class not found (If the jar is in
classpath):
{code}
a = load '/user/pig/tests/data/zebra/singlefile/studentsortedtab10k' using
org.apache.hadoop.zebra.pig.TableLoader('', 'sorted');
b = load '/user/pig/tests/data/zebra/singlefile/votersortedtab10k' using
org.apache.hadoop.zebra.pig.TableLoader('', 'sorted');
g = cogroup a by $0, b by $0 using 'merge';
store g into '/user/pig/out/jianyong.1304374720/ZebraMapCogrp_1.out';
{code}
If we use register, the error goes away. However, Pig always ship jars
containing LoadFunc automatically. It should be the same for merged
cogroup/join.
