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

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
