1.在[Hive][]\-site.xml中加

**\[html\]**  [view plain][]   [copy][view plain]

[print][view plain] [?][view plain] [![在CODE上查看代码片][CODE]][CODE_CODE] [![派生到我的代码片][ico_fork.svg]][ico_fork.svg 1]

1.    
     <property>  
      <name>hive.server2.authentication</name>  
        <value>CUSTOM</value>  
     </property>  
      
      
    <property>  
      <name>hive.server2.custom.authentication.class</name>  
        <value>com.hive.SampleAuthenticator</value>  
     </property>

设置server2验证方式是CUSTOM  ；并指定自定义验证类是org.apache.hadoop.hive.contrib.auth.XXXXPasswdAuthenticator

2.完成自定义验证类org.apache.[Hadoop][].hive.contrib.auth.XXXXPasswdAuthenticator,继承org.apache.hive.service.auth.PasswdAuthenticationProvider

重写方法，如下：

**\[java\]**  [view plain][]   [copy][view plain]

[print][view plain] [?][view plain] [![在CODE上查看代码片][CODE]][CODE_CODE] [![派生到我的代码片][ico_fork.svg]][ico_fork.svg 1]

1.  package com.hive;  
      
      
    import java.util.Hashtable;  
    import javax.security.sasl.AuthenticationException;  
    import org.apache.hive.service.auth.PasswdAuthenticationProvider;  
      
      
    /\*  
     javac -cp $HIVE\_HOME/lib/hive-service-0.12.0-cdh5.0.0-beta-2.jar SampleAuthenticator.java -d .  
     jar cf sampleauth.jar hive  
     cp sampleauth.jar $HIVE\_HOME/lib/.  
    \*/  
      
      
      
      
    public class SampleAuthenticator implements PasswdAuthenticationProvider \{  
      
      
      Hashtable<String, String> store = null;  
      
      
      public SampleAuthenticator () \{  
        store = new Hashtable<String, String>();  
        store.put("root", "123");  
        store.put("hive", "123");  
      \}  
      
      
      @Override  
      public void Authenticate(String user, String  password)  
          throws AuthenticationException \{  
      
      
        String storedPasswd = store.get(user);  
      
      
        if (storedPasswd != null && storedPasswd.equals(password))  
          return;  
      
      
        throw new AuthenticationException("SampleAuthenticator: Error validating user");  
      \}  
      
      
    \}

3.打jar包放到hive\\lib下。注意,jar包中的目录结构和org.apache.hadoop.hive.contrib.auth.XXXXPasswdAuthenticator是一致的。

4.重启HiveServer2服务；
