jdbc impala连接hive

 import java.sql.Connection; import java.sql.Driver; import java.sql.PreparedStatement; import java.sql.ResultSet; import java.sql.SQLException; import java.util.Properties; public class TestConnection { public static void main(String[] args) throws InstantiationException, IllegalAccessException, ClassNotFoundException, SQLException { Driver driver = (Driver) Class.forName("com.cloudera.impala.jdbc41.Driver").newInstance(); Properties propertes = new Properties(); Connection connetction = driver .connect("jdbc:impala://192.168.44.141:21051/data;AuthMech=3;UID=hive;PWD=hive", propertes); // 使用第三种安全验证 String sql = "SELECT * FROM data.article a WHERE id=?"; PreparedStatement stmt = connetction.prepareStatement(sql); stmt.setString(1, "100"); ResultSet rs = stmt.executeQuery(); System.out.println("完成执行==============================="); if (rs.next()) { System.out.println("返回：" + rs.getObject(1)); } rs.close(); connetction.close(); } } 

在pom.xml中引入依赖包，其中jar包到${project.basedir}/src/main/webapp/WEB-INF/lib/目录中
