There are ODBC drivers available for Hive, though they aren’t part of the open source package and are not free. Google can help you find them. As Elliot says, you can use the Thrift protocol, which is what the JDBC driver uses. You can find the thrift definition in the code at https://github.com/apache/hive/blob/master/service-rpc/if/TCLIService.thrift
