[jira] [Created] (DRILL-2321) FlattenRecordBatch should transfer vectors honoring output field reference.

Hanifi Gunes created DRILL-2321:
-----------------------------------

             Summary: FlattenRecordBatch should transfer vectors honoring output field reference.
                 Key: DRILL-2321
                 URL: https://issues.apache.org/jira/browse/DRILL-2321
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Hanifi Gunes
            Assignee: Hanifi Gunes


Current implementation of FlattenRecordBatch does not create transfer pairs with the target vector named with the desired field reference. This seems working fine with repeated types as the upstream project or ArrayPathSegment makes the renaming implicitly. Overall relying on upstream makes the code fragile. Also, DRILL-2150 requires this patch as it alters the way repeated vectors are modeled. This patch proposes to implement a less fragile transfer pair handling via explicit naming.
