Using HiveServer2 - Authentication

To configure Hive for use with HiveServer2, include the following configuration properties in the .../hive-site.xml configuration file.

<property>
  <name>hive.support.concurrency</name>
  <description>Enable Hive's Table Lock Manager Service</description>
  <value>true</value>
</property>

<property>
  <name>hive.zookeeper.quorum</name>
  <description>Zookeeper quorum used by Hive's Table Lock Manager</description>
  <value><zk node1>,<zk node2>,...,<zk nodeN></value>
</property>

<property>
  <name>hive.zookeeper.client.port</name>
  <value>5181</value>
  <description>The Zookeeper client port. The MapR default clientPort is 5181.</description>
</property>

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

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;
}

e.g.

ackage 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:

<property>
  <name>hive.server2.authentication</name>
  <value>CUSTOM</value>
</property>

<property>
  <name>hive.server2.custom.authentication.class</name>
  <value>org.apache.hadoop.hive.contrib.auth.XXXXPasswdAuthenticator</value>
</property>

User name and password would be set in hive-site.xml

<property>
    <name>hive.jdbc_passwd.auth.hive_user1</name>
    <value>b531c271de4552ca2dec510d318c87f9</value>
    <description/>
</property>
<property>
    <name>hive.jdbc_passwd.auth.hive_user2</name>
    <value>b531c271de4552ca2dec510d318c87f9</value>
    <description/>
</property>
