在Phoenix-4.0.0（注意要配合hbase0.98.1+，否則會拋異常）的安裝目錄下，有hadoop-1和hadoop-2,目錄，目錄中有phoenix-4.0.0-incubating-client.jar將其拷貝到工程目錄下，我用的是Hadoop1

然後就可以通過jdbc來訪問phoenix資料介面。

查詢的程式碼

package org.tcse.electric.local;


import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;


public class TestConnectPhoenix {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		try {
            Class.forName("org.apache.phoenix.jdbc.PhoenixDriver");
        } catch(ClassNotFoundException ex) {
            ex.printStackTrace();
        }
		try {
			Connection conn = DriverManager
					.getConnection("jdbc:phoenix:133.133.134.188");
			Statement statement = conn.createStatement();
			ResultSet ret = statement.executeQuery("select * from ph_devices");
			while(ret != null && ret.next())
			{
//				System.out.println(ret);
				System.out.println(ret.getString(1));
				System.out.println(ret.getString(2));
			}
		} catch (SQLException e) {
