[jira] [Created] (PIG-3492) ColumnPrune dropping used column due to LogicalRelationalOperator.fixDuplicateUids changes not propagating

Koji Noguchi created PIG-3492:
---------------------------------

             Summary: ColumnPrune dropping used column due to LogicalRelationalOperator.fixDuplicateUids changes not propagating
                 Key: PIG-3492
                 URL: https://issues.apache.org/jira/browse/PIG-3492
             Project: Pig
          Issue Type: Bug
    Affects Versions: 0.11.1, 0.12.1, 0.13.0
            Reporter: Koji Noguchi


I don't have a testcase I can upload at the moment, but here's my observation.

SplitFilter -> schemaResetter -> LOGenerate.getSchema -> LogicalRelationalOperator.fixDuplicateUids() creating a new UID but that UID is not propagated to the entire plan (since SplitFilter.reportChanges only returns subplan).

As a result, I am seeing ColumnPruning cutting off those used columns.
