What version of Drill are you using? I would recommend using ODBC v1.3.16
Did you define data types in your view? Tableau with the ODBC driver may use the execution of a LIMIT 0 query when trying to collect metadata, with a poorly defined view it can potentially cause issues pending the underlying data.
