Creating external tables from SQL Server using JDBC Drivers I am trying to query Hive tables AND Kylin tables from SQL Server 2019. I was doing some research and found that MSSQL provide PolyBase as a form of interface to Hadoop storage. However, the examples mostly include creating tables and storing file formats into HDFS. All I need is to create an external table from MSSQL using JDBC drivers. Is this possible? I would like to avoid using ODBC drivers.
