具体从网上看

http://doc.mapr.com/display/MapR/Using+HiveServer2#UsingHiveServer2-ConfiguringCustomAuthentication

一共提供了三种安全认证方式，我们通常采用的为第三种自定义的方式。

To implement custom authentication for HiveServer2, create a custom Authenticator class derived from the following interface:

从这段话看出来我们要实现一个接口：PasswdAuthenticationProvider (org.apache.hive.service.auth.PasswdAuthenticationProvider)我们来看看这个接口

public interface PasswdAuthenticationProvider {

/**

* The Authenticate method is called by the HiveServer2 authentication layer

* to authenticate users for their requests.

* If a user is to be granted, return nothing/throw nothing.

* When a user is to be disallowed, throw an appropriate {@link AuthenticationException}.

*

* For an example implementation, see {@link LdapAuthenticationProviderImpl}.

*

* @param user - The username received over the connection request

* @param password - The password received over the connection request

* @throws AuthenticationException - When a user is found to be

* invalid by the implementation

*/

void Authenticate(String user, String password) throws AuthenticationException;

}

有一个方法要实现，实现了这个接口就可以自定义验证用户名密码了。代码不是太多

package org.apache.hadoop.hive.contrib.auth;

import javax.security.sasl.AuthenticationException;

import org.apache.commons.logging.Log;

import org.apache.commons.logging.LogFactory;

import org.apache.hadoop.conf.Configurable;

import org.apache.hadoop.conf.Configuration;

import org.apache.hadoop.hive.contrib.utils.MD5Util;

import org.apache.hive.service.auth.PasswdAuthenticationProvider;

public class XXXXPasswdAuthenticator implements PasswdAuthenticationProvider,Configurable {

private static final Log LOG=LogFactory.getLog(XXXXPasswdAuthenticator.class);

private Configuration conf=null;

private static final String HIVE_JDBC_PASSWD_AUTH_PREFIX="hive.jdbc_passwd.auth.%s";

public XXXXPasswdAuthenticator() {

init();

}

/**

*

*/

public void init(){

}

@Override

public void Authenticate(String userName, String passwd)

throws AuthenticationException {

LOG.info("user: "+userName+" try login.");

String passwdMD5 = getConf().get(String.format(HIVE_JDBC_PASSWD_AUTH_PREFIX, userName));

if(passwdMD5==null){

String message = "user's ACL configration is not found. user:"+userName;

LOG.info(message);

throw new AuthenticationException(message);

}

String md5 = MD5Util.md5Hex(passwd);

if(!md5.equals(passwdMD5)){

String message = "user name and password is mismatch. user:"+userName;

throw new AuthenticationException(message);

}

LOG.info("user "+userName+" login system successfully.");

}

@Override

public Configuration getConf() {

if(conf==null){

this.conf=new Configuration();

}

return conf;

}

@Override

public void setConf(Configuration arg0) {

this.conf=arg0;

}

}

Add the following properties to the hive-site.xml file, then restart Hiveserver2:

开启自定义验证配置

hive.server2.authentication

CUSTOM

hive.server2.custom.authentication.class

org.apache.hadoop.hive.contrib.auth.XXXXPasswdAuthenticator

相信看懂代码的人应该明白怎么做了，我们要把用户名密码配置到hive-site.xml配置文件中。

hive.jdbc_passwd.auth.hive_r

b531c271de4552ca2dec510d318c87f9

多个用户可以添加多个property，里面配置的即用户名密码了。

以上代码打包jar包，上传到hive/lib下即可实现HiveServer2的安全策略之自定义用户名密码验证了。
