Viraj Bhat commented on PIG-2069:
---------------------------------
Daniel is this an issue since Multiquery optimization was introduced (0.6,
0.7), or is this specific to Pig 0.8 and 0.9.
> 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.
