> Key: DRILL-902
> URL: https://issues.apache.org/jira/browse/DRILL-902
> Project: Apache Drill
> Issue Type: Bug
> Components: Execution - Flow
> Reporter: Mehant Baid
> Assignee: Mehant Baid
> Priority: Minor
>
> Currently OutputMutator allows adding two fields with the same name but
> different MajorType to the RecordBatch. This could potentially cause
> problems.
> We need to maintain a map of the field names as they are added to the batch
> and throw an exception if a field with same name is added twice.
