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
- beeline> !connect jdbc:hive2://feng02:10000 jifeng jifeng org.apache.hive.jdbc.HiveDriver
- Connecting to jdbc:hive2://feng02:10000
- log4j:WARN No appenders could be found for logger (org.apache.thrift.transport.TSaslTransport).
- log4j:WARN Please initialize the log4j system properly.
- log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

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
