使用eclipse远程连接hive---基于CDH5

我已经用cloudera manager安装好了CDH5.4.10上面的hive连接配置：
由于我的server2和hive都是在master01上面启动好了的，因此，我只需要测试连接即可

基础环境：
CDH 5.4.10
hadoop 2.6.0
hive  1.1.0
hbase 1.0.0
zookeeper  3.4.5
sqoop 1.4.5
jdk 1.7.0_67
os  centos6.5


[root@master01 ~]# cd /opt/cloudera/parcels/CDH-5.4.10-1.cdh5.4.10.p0.16/bin/
[root@master01 bin]# ./beeline
Beeline version 1.1.0-cdh5.4.10 by Apache Hive
beeline>

beeline> !connect jdbc:hive2://192.168.1.207:10000
Connecting to jdbc:hive2://192.168.1.207:10000
Enter username for jdbc:hive2://192.168.1.207:10000: root
Enter password for jdbc:hive2://192.168.1.207:10000: ****   --root/root直接连上了！
Connected to: Apache Hive (version 1.1.0-cdh5.4.10)
Driver: Hive JDBC (version 1.1.0-cdh5.4.10)
Transaction isolation: TRANSACTION_REPEATABLE_READ
0: jdbc:hive2://192.168.1.207:10000>


先来创建几个表，导入点数据，方便后面操作:
[root@master01 bin]# hive
Logging initialized using configuration in jar:file:/opt/cloudera/parcels/CDH-5.4.10-1.cdh5.4.10.p0.16/jars/hive-common-1.1.0-cdh5.4.10.jar!/hive-log4j.properties
WARNING: Hive CLI is deprecated and migration to Beeline is recommended.
hive>
hive> create table runningrecord_old(id int,systemno string,longitude string,latitude string,speed string,direction smallint,elevation string,acc string,islocation string,mileage string,oil string,currenttime timestamp,signalname string,currentvalue string) row format delimited fields terminated by ',';
OK
Time taken: 2.607 seconds
hive> load data local inpath '/tmp/rtest.txt' into table runningrecord_old;

OK
Time taken: 1.575 seconds

eclipse安装在我的win7系统上
下一步，我们拷贝jar包到eclipse项目中去：
新建java project：hiveconnect
新建class：hiveconnecttest
新建folder：lib/    跟src同级

[root@master01 jars]# cd /opt/cloudera/parcels/CDH-5.4.10-1.cdh5.4.10.p0.16/jars
[root@master01 jars]# sz hive*.jar   下载包放到刚刚那个lib目录下：d:/workspace/hiveconnect/lib/
[root@master01 jars]# sz hadoop*.jar
[root@master01 jars]# ll hive*.jar

添加到build path
之前忘记添加hadoop的核心包，就会出现下列报错，测试一次程序报错:
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/conf/Configuration

测试ok，测试结果如下：
连接：org.apache.hive.jdbc.HiveConnection@43a25848
是否有数据：true
Running:show tables 'tinatest'
执行“show tables”运行结果:
tinatest
Running:describe tinatest
执行“describe table”运行结果:
key int
value string
Running:load data local inpath '/tmp/test2.txt' into table tinatest
Running:select * from tinatest
执行“select * query”运行结果:

2 b
3 tina


hiveconnecttest.java的具体内容：---网上找的例子随意改了一下，测试基础功能即可。
package hiveconnect;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;
import org.apache.hadoop.conf.Configuration;

public class hiveconnecttest {
    private static String sql = ""; 
    private static ResultSet res; 

public static void main(String[] args)throws Exception {
// TODO Auto-generated method stub 
Class.forName("org.apache.hive.jdbc.HiveDriver"); 
Connection conn=DriverManager.getConnection("jdbc:hive2://192.168.1.207:10000","root","root");
System.out.println("连接："+conn);
Statement stmt=conn.createStatement();
String query_sql="select systemno from runningrecord_old limit 1";
ResultSet rs=stmt.executeQuery(query_sql);
System.out.println("是否有数据："+rs.next());

//创建的表名 
String tableName = "tinatest"; 

/** 第一步:存在就先删除 **/ 
sql = "drop table " + tableName; 
stmt.execute(sql); 

/** 第二步:不存在就创建 **/ 
sql = "create table " + tableName + " (key int, value string)  row format delimited fields terminated by ','"; 
stmt.execute(sql); 

// 执行“show tables”操作 
sql = "show tables '" + tableName + "'"; 
System.out.println("Running:" + sql); 
res = stmt.executeQuery(sql); 
System.out.println("执行“show tables”运行结果:"); 
if (res.next()) { 
        System.out.println(res.getString(1)); 
}

// 执行“describe table”操作 
sql = "describe " + tableName; 
System.out.println("Running:" + sql); 
res = stmt.executeQuery(sql); 
System.out.println("执行“describe table”运行结果:"); 
while (res.next()) {   
        System.out.println(res.getString(1) + "\t" + res.getString(2)); 
} 
// 执行“load data into table”操作 
String filepath = "/tmp/test2.txt"; 
sql = "load data local inpath '" + filepath + "' into table " + tableName; 
System.out.println("Running:" + sql); 
stmt.executeUpdate(sql); 
// 执行“select * query”操作 
sql = "select * from " + tableName; 
System.out.println("Running:" + sql); 
res = stmt.executeQuery(sql); 
System.out.println("执行“select * query”运行结果:"); 
while (res.next()) { 
        System.out.println(res.getInt(1) + "\t" + res.getString(2)); 
} 
conn.close(); 
conn = null; 
}
}

在学习阶段，不对的地方欢迎指正。
