      Impala translator can handle reserved words in queries by quoting but doing select * the query fails in an unhelpful way. Example:
      --succeeds
      select calendar_type,
      start_date,
      calendar_year,
      quarter_structure,
      date_key,
      'month',
      week,
      day_of_month
      from warehouse.dim_advertiser_calendar;

      fails due to reserved word "month" as a column in the virtual table:
      select * from warehouse.dim_advertiser_calendar;

            Added the missing quoting.

            We should probably change the default import to use JDBC DatabaseMetaData now that support has matured.

            This happens when using the default import, but not with the useDatabaseMetaData option correct?
