             Summary: Validate column names for strongly-typed tables such as parquet
                 Key: DRILL-872
                 URL: https://issues.apache.org/jira/browse/DRILL-872
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Steven Phillips


Currently, parquet tables, like other filesystem tables, are treated as schema-less tables. But it would make sense to get the schema by reading and merging the footers from all of the parquet files. This will allow drill to validate whether a requested column exists, and throw an error before running the query. It will also remove the need to qualify columns with the table name or alias when doing a join.
