-------------------------------------
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.
