If you are using the HiveServer2 then try using below code snippet:

private static String driver = "org.apache.hive.jdbc.HiveDriver";
.
.
.
    Connection connect = DriverManager.getConnection("jdbc:hive2://<host>:port/default","","");
    Statement state = connect.createStatement();
   // Query to show tables
    String show = "show tables";
    ResultSet res = state.executeQuery(show);

I am using Hive Version 0.13 with that I am using Hive Driver version 1.1.0 My POM Dependency for Hive Driver: org.apache.hive hive-jdbc 1.1.0
