Hi,

Maybe you could share the java source code doing the connection ?

Here is a really small working sample :

public class ManageHive {

   private static String driverName = "org.apache.hive.jdbc.HiveDriver";
   private static Logger logger = Logger.getLogger(ManageHive.class);
 
   public static Connection getConnection(LoadProperties prop, String user) throws ClassNotFoundException, SQLException {
 
      String hiveJdbc = prop.getPropertyByName("hive_jdbc");
 
      try {
         Class.forName(driverName);
      } catch (ClassNotFoundException e) {
         e.printStackTrace();
         throw e;
      }
      Connection conn2 = DriverManager.getConnection(hiveJdbc+"/extraction", user, "");
      return conn2;
   }
 
   public static void execSql(LoadProperties prop, String user, String sql) throws SQLException, ClassNotFoundException {
 
      Connection maConn = getConnection(prop,user);
      Statement stmt = maConn.createStatement();
 
      int result = stmt.executeUpdate(sql);
      if ( result == Statement.EXECUTE_FAILED ) {
         throw new SQLException("Erreur d'execution.");
      }
   }
}
