LoadFunc jar does not ship to backend in MultiQuery case
--------------------------------------------------------
Key: PIG-2069
URL: https://issues.apache.org/jira/browse/PIG-2069
Project: Pig
Issue Type: Bug
Affects Versions: 0.8.1, 0.9.0
Reporter: Daniel Dai
Fix For: 0.9.0
Pig is able to automatically figure out the jar containing the LoadFunc and
ship them to backend. However, the following script didn't:
{code}
A = load '1.txt' using SomeLoadFunc();
B = filter A by $0==0;
C = filter A by $1==1;
D = join B by $0, C by $0;
dump D;
{code}
The reason is this query is a multiquery (A is reused and thus create an
implicit split). When we merge multiquery into one job, we didn't merge udfs
list properly.
