本文介绍了如何在Spark环境中利用ThriftJDBC/ODBC服务器连接Hive，并通过beeline进行测试。展示了从配置到查询Hive表的全过程，包括端口设置、服务器地址、Spark master、驱动类路径等关键参数，以及如何使用beeline进行连接和执行SQL查询。此外，还提供了使用Java JDBC进行连接和查询的具体示例。

Running the Thrift JDBC/ODBC server

1:运行

./sbin/start-thriftserver.sh --hiveconf hive.server2.thrift.port=10000 --hiveconf hive.server2.thrift.bind.host=feng02 --master spark://feng02:7077 --driver-class-path /home/jifeng/hadoop/spark-1.2.0-bin-2.4.1/lib/mysql-connector-java-5.1.32-bin.jar --executor-memory 1g

端口:10000

服务器:feng02

spark master:spark://feng02:7077

driver-class-path:mysql驱动包(hive配置的)

[jifeng@feng02 spark-1.2.0-bin-2.4.1]$ ./sbin/start-thriftserver.sh  --hiveconf hive.server2.thrift.port=10000  --hiveconf hive.server2.thrift.bind.host=feng02 --master spark://feng02:7077 --driver-class-path /home/jifeng/hadoop/spark-1.2.0-bin-2.4.1/lib/mysql-connector-java-5.1.32-bin.jar
starting org.apache.spark.sql.hive.thriftserver.HiveThriftServer2, logging to /home/jifeng/hadoop/spark-1.2.0-bin-2.4.1/sbin/../logs/spark-jifeng-org.apache.spark.sql.hive.thriftserver.HiveThriftServer2-1-feng02.out

2:运行beeline

Now you can use beeline to test the Thrift JDBC/ODBC server:

./bin/beeline

[jifeng@feng02 spark-1.2.0-bin-2.4.1]$ ./bin/beeline
Spark assembly has been built with Hive, including Datanucleus jars on classpath
Beeline version ??? by Apache Hive

3:连接server

参考：https://cwiki.apache.org/confluence/display/Hive/HiveServer2+Clients#HiveServer2Clients-BeelineExample

beeline> !connect jdbc:hive2://feng02:10000 jifeng jifeng org.apache.hive.jdbc.HiveDriver

4：查询

0: jdbc:hive2://feng02:10000> show tables;                                                                  
+----------------+

4:Java JDBC连接

package demo.test;

import java.sql.*;

public class Pretest {


		    public static void main( String args[] )
		        throws SQLException , ClassNotFoundException {
	    	    String jdbcdriver="org.apache.hive.jdbc.HiveDriver";
	    	    String jdbcurl="jdbc:hive2://feng02:10000";
	    	    String username="scott";
	    	    String password="tiger";		
	    	    Class.forName(jdbcdriver);
	    	    Connection c = DriverManager.getConnection(jdbcurl,username,password); 
		        Statement st = c.createStatement();		        
		        print( "num should be 1 " , st.executeQuery("select * from student"));

		        // TODO indexing
		    }
			 static void print( String name , ResultSet res )
				        throws SQLException {
				        System.out.println( name);
				        ResultSetMetaData meta=res.getMetaData();				        
		                //System.out.println( "\t"+res.getRow()+"条记录");
		                String	str="";
		                for(int i=1;i<=meta.getColumnCount();i++){
		                	str+=meta.getColumnName(i)+"   ";
		                	//System.out.println( meta.getColumnName(i)+"   ");
		                }
		                System.out.println("\t"+str);
		                str="";
				        while ( res.next() ){
				        	for(int i=1;i<=meta.getColumnCount();i++){	
				        		str+= res.getString(i)+"   ";				        	} 
				        	System.out.println("\t"+str);
				        	str="";
				        }
				    }	    
}

上面是运行参数

结果显示：

num should be 1 
	id   name   age   
	1   nick   24   
	2   doping   25   
	3   caizhi   26   
	4   liaozhi   27   
	5   wind   30
