Question

因为我导入了所有必需的JAR文件，如上图所示。但是在尝试通过java程序连接hive2时，它仍然会出错。

错误让我在这一行。

Connection connect = DriverManager.getConnection（“jdbc：hive2：// localhost：10000 / default”，“”，“”）;

错误：

18/05/30 17:12:15 INFO jdbc.Utils: Supplied authorities: localhost:10000
18/05/30 17:12:15 INFO jdbc.Utils: Resolved authority: localhost:10000

    at Hive_java.main(Hive_java.java:15)

JAVA代码：

import java.sql.SQLException;
import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.Statement;
import java.sql.DriverManager;
public class Hive_java{
  private static String driver = "org.apache.hive.jdbc.HiveDriver";  //driver used for hiveserver2
  public static void main(String[] args) throws SQLException {
    try {
      Class.forName(driver);
    } catch (ClassNotFoundException e) {
      e.printStackTrace();
      System.exit(1);
    }
    Connection connect = DriverManager.getConnection("jdbc:hive2://localhost:10000/default", "", "");   //connecting to default database
    Statement state = connect.createStatement();
    System.out.println("!!!!!!!!!!Running 1st query!!!!!!!!!!");
    System.out.println("Listing tables in hive");
    ResultSet show_tables = state.executeQuery("show tables");
    while (show_tables.next()) {
        System.out.println(show_tables.getString(1));
    }
    System.out.println("!!!!!!!!!!Running 2nd query!!!!!!!!!!");
    System.out.println("Describing slave3_tbl table");
    ResultSet describe_table = state.executeQuery("describe slave3_tbl");
    while (describe_table.next()) {
        System.out.println(describe_table.getString(1) + "\t" + describe_table.getString(2));
      }
  }
}

无法通过JDBC java程序连接hive2
