In addition to the hive and beeline command-line tools, it is possible to submit HiveQL queries to the system via the JDBC and Thrift programmatic interfaces. Support for ODBC was bundled in older versions of Hive, but as of Hive 0.12, it needs to be built from scratch. More information on this process can be found at https://cwiki.apache.org/confluence/display/Hive/HiveODBC.
A Hive client written using JDBC APIs looks exactly the same as a client program written for other database systems (for example MySQL). The following is a sample Hive client program using JDBC APIs. The source code for this example can be found at https://github.com/learninghadoop2/book-examples/blob/master/ch7/clients/com/learninghadoop2/hive/client/HiveJdbcClient.java.
public class HiveJdbcClient {
private static String driverName = " org.apache.hive.jdbc.HiveDriver";
// connection string
public static String URL = "jdbc:hive2://localhost:10000";
// Show all tables...
