Nate Putnam updated DRILL-5292:
-------------------------------
    Affects Version/s: 1.10.0

> Better Parquet handling of sparse columns
> -----------------------------------------
>
>                 Key: DRILL-5292
>                 URL: https://issues.apache.org/jira/browse/DRILL-5292
>             Project: Apache Drill
>          Issue Type: Improvement
>          Components: Storage - Parquet
>    Affects Versions: 1.10.0

> It appears the current implantation of ParquetRecordReader will fill in missing columns
between files as a NullableIntVector. It would be better if the code could determine if that
column was defined in a different file (and didn't conflict) and use the defined data type.
