Summary: Custom Partitioner not working with MultiQueryOptimizer
Key: PIG-3435
URL: https://issues.apache.org/jira/browse/PIG-3435
Project: Pig
Issue Type: Bug
Components: impl
Reporter: Koji Noguchi

When looking at PIG-3385, noticed some issues in handling of custom partitioner
with multi-query optimization.

C1 = group B1 by col1 PARTITION BY
org.apache.pig.test.utils.SimpleCustomPartitioner parallel 2;
C2 = group B2 by col1 PARTITION BY
org.apache.pig.test.utils.SimpleCustomPartitioner parallel 2;
{noformat}
This seems to be merged to one mapreduce job correctly but custom partitioner
information was lost.

C2 = group B2 by col1 parallel 2;

This seems to be merged even though they should run on two different
partitioner.
