Невозможно подключиться к Hive через приложение Java. ⇐ JAVA

[Anonymous]

Я пытаюсь подключиться к Hive2 через приложение Java, но получаю следующую ошибку:

Exception in thread "main" java.sql.SQLException: [Simba][HiveJDBCDriver](500310) Invalid operation: Peer indicated failure: Unsupported mechanism type PLAIN;

Я использовал следующую документацию для Cloudera: https://www.cloudera.com/documentation/ ... -jdbc/2-5- 4.html
Любая помощь будет оценена по достоинству. Я пытаюсь использовать следующую строку подключения: - Connection con = DriverManager.getConnection("jdbc:hive2://server.com:12345/default;principal=hive/_org.COM","user_id","pwd");< /code>

полный код:

package hive2;
import java.sql.SQLException;
import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.Statement;

import java.sql.DriverManager;

public class hive {
private static String driverName = "com.cloudera.hive.jdbc4.HS2Driver";

public static void main(String[] args) throws SQLException {
try {
Class.forName(driverName);
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
System.exit(1);
}

Connection con = DriverManager.getConnection("jdbc:hive2://server.com:12345/default;principal=hive/_org.COM","user_id","pwd");
Statement stmt = con.createStatement();
String tableName = "testHiveDriverTable";
stmt.executeQuery("drop table " + tableName);
ResultSet res = stmt.executeQuery("create table " + tableName + " (key int, value string)");
// show tables
String sql = "show tables '" + tableName + "'";
System.out.println("Running: " + sql);
res = stmt.executeQuery(sql);
if (res.next()) {
System.out.println(res.getString(1));
}
// describe table
sql = "describe " + tableName;
System.out.println("Running: " + sql);
res = stmt.executeQuery(sql);
while (res.next()) {
System.out.println(res.getString(1) + "\t" + res.getString(2));
}

// load data into table
// NOTE: filepath has to be local to the hive server
// NOTE: /tmp/a.txt is a ctrl-A separated file with two fields per line
String filepath = "/tmp/a.txt";
sql = "load data local inpath '" + filepath + "' into table " + tableName;
System.out.println("Running: " + sql);
res = stmt.executeQuery(sql);

// select * query
sql = "select * from " + tableName;
System.out.println("Running: " + sql);
res = stmt.executeQuery(sql);
while (res.next()) {
System.out.println(String.valueOf(res.getInt(1)) + "\t" + res.getString(2));
}

// regular hive query
sql = "select count(1) from " + tableName;
System.out.println("Running: " + sql);
res = stmt.executeQuery(sql);
while (res.next()) {
System.out.println(res.getString(1));
}
}
}
