-------------------------------------

             Summary: Union All qiery fails stating that parquet files are schema less
                 Key: DRILL-4958
                 URL: https://issues.apache.org/jira/browse/DRILL-4958
             Project: Apache Drill
          Issue Type: Bug
          Components: Execution - Flow
    Affects Versions: 1.9.0
            Reporter: Khurram Faraaz


UNION ALL query over parquet files fails and reports that the Union-All was over schema-less
tables.
Parquet files are not with out a schema, they do have metadata. We need to fix this. Postgres
returns results for the same query on same data.

Drill 1.9.0
