The error message indicates Tableau is having trouble connecting to your "ShowData" data source and there's an issue with the SQL query it's trying to run on your Hive database. Let's break down the error and potential solutions: Error Breakdown: Bad Connection: Tableau can't establish a connection to the Hive database. Error Code: B19090E0: Generic Tableau error for connection issues. Error Code: 10002: Hive specific error related to the SQL query. SQL state: TStatus(statusCode:ERROR_STATUS): Hive is encountering an error during query processing. Invalid column reference 'tableausql.fieldname': The specific error points to an invalid column reference in the query. Potential Solutions: Verify Database Connection: Ensure the Hive server is running and accessible from Tableau. Double-check the connection details in your Tableau data source configuration, including server address, port, username, and password. Review SQL Query: The error message highlights "tableausql.fieldname" as an invalid column reference. Check if this field name actually exists in your Hive table. There might be a typo or a case-sensitivity issue. If "tableausql" is a prefix Tableau adds, ensure it's not causing conflicts with your actual column names. Check for Unsupported Functions: In rare cases, Tableau might try to use functions not supported by Hive.
