hive java api

1.启动 hadoop
start-all.sh

2.启动hive
./hive --service hiveserver2

3.新建Java 工程
导入jar包
导入hive\lib目录下的hive-jdbc-1.2.0-standalone.jar
导入hadoop-2.7.1\share\hadoop\common下的hadoop-common-2.7.1.jar

4.编写jdbc代码执行
Class.forName("org.apache.hive.jdbc.HiveDriver");
Connection conn = DriverManager.getConnection("jdbc:hive2://192.168.242.101:10000/park","root","root");
Statement statement = conn.createStatement();
//statement.executeUpdate("create table x2xx (id int,name string)");
statement.close();
conn.close();

public class HiveJDBC {

	public static void main(String args[]) throws Exception{
		
		Class.forName("org.apache.hive.jdbc.HiveDriver");
		Connection conn = DriverManager.getConnection("jdbc:hive2://192.168.76.131:10000/park","root","zhangbiao");
		PreparedStatement ps = conn.prepareStatement("select * from ext_student");
		ResultSet rs = ps.executeQuery();
		while(rs.next()){
			System.out.println("id:"+rs.getString(1)+" name:"+rs.getString(2));
		}
		rs.close();
		ps.close();
		conn.close();

	}
