Hive2 JDBC错误

Question

I'm trying to connect to a Hive2 database but I'm getting the following error:

java.lang.NoSuchFieldError: HIVE_SERVER2_TRANSPORT_MODE

Here's the code I'm trying to run. Basically, I'm just trying to connect to the hive2 databse and populate a jTable with the results of a user-defined query:

    /**

    public SQLSelect() {

    }

    private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         
                Cursor cursor = Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR); 
                setCursor(cursor);

                try {
            Class.forName("org.apache.hive.jdbc.HiveDriver");
                        //Class.forName("org.apache.hadoop.hive.jdbc.HiveDriver");
        } catch (ClassNotFoundException e) {
            // TODO Auto-generated catch block

        }
        try {

                String locationString = "jdbc:hive2://" + jTextField1.getText() + ":" + jTextField2.getText();
                String userString = jTextField3.getText();
                char password[] = jPasswordField1.getPassword();
                String pString = new String(password);

                System.out.println(locationString + userString + pString);

                Connection conn = DriverManager.getConnection(locationString,userString,pString);

        //Connection conn = DriverManager.getConnection("jdbc:hive://76.99.192.2:9999","user","password");
        s = conn.createStatement();
        r = s.executeQuery(jTextArea1.getText());
        //System.out.println(r.getNString(1));
        }
        catch (Exception e)
        {
                        setCursor(Cursor.DEFAULT_CURSOR);
                        JOptionPane.showMessageDialog(null, e.getMessage(), "SQL Error", JOptionPane.ERROR_MESSAGE);
            jLabel9.setText(e.getMessage());
        }
                try {
                MainPanel resultsPanel = new jdbctohive.MainPanel();
                resultsPanel.jTable1.setModel(DbUtils.resultSetToTableModel(r));
                resultsPanel.setTitle("Hive SQL Management Studio");
                resultsPanel.setVisible(true);

                setCursor(Cursor.DEFAULT_CURSOR);
                this.setVisible(false);
                }

                catch (Exception e)
                {
                    setCursor(Cursor.DEFAULT_CURSOR);
                }

Any help would be much appreciated!

Answer 1

I was finally able to connect. My previous statement suggested to use the ";auth=noSasl" which turned out to be wrong. After many attempts, this was the code that finally worked. As I was working in windows, I had problems with the Hadoop Win version requiring winutils.exe. Since HortonWorks had a Win implementation for 1.3 of their product, I downloaded it and extracted the file out of the .MSI file. You may not need this, if working in linux. One of the keys I found was to implement jdbc and hadoop logging, as without these, I simple was stuck on the getConnection never returning... But, there were underlying errors that I just assumed word return as stacktrace, but did not. Good Luck.
