    The Hadoop Hive engine was unable to execute the query - Error loading Extract Refresh

    Andrew Owens

      I've been running the same query for quite a long time on Impala (not Hive, despite the warning below) and am quite confused as to why the queries are failing to execute from Tableau Server.

       

      I have retested each of the queries within the dashboard against Impala itself and they've executed successfully, however as of midnight last night they have stopped executing successfully and have been throwing the following errors.

      Does anyone know if this is some sort of driver error? I'm slightly confused as to why Hive is mentioned at all as all my connections are set to 'Impala'.
