Java – Simple user/password authentication for HiveServer2 (no Kerberos/LDAP)

How do I provide simple properties file or database user/password authentication for HiveServer2?

I’ve found this introduction to this, but it’s not in English :(.
About Cloudera reference manual They talk about the hive.server2.authentication property. It supports the CUSTOM implementation of interface hive.server2.custom.authentication.

How to achieve this?

Essentially, you must provide a Java application that can perform authentication. Maybe you’re licensing a mysql or postgres database or flat files, etc. You need to provide a jar that implements the org.apache.hive.service.auth.PasswdAuthenticationProvider interface.

A simple example:

package org.apache.hive.service.auth.PasswdAuthenticationProvider.SampleAuth;

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("user1", "passwd1");
    store.put("user2", "passwd2");
  }

@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");
  }

}

Then in hive-site.xml, use your newly created custom authentication jar:

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

<property>
  <name>hive.server2.custom.authentication.class</name>
  <value>org.apache.hive.service.auth.PasswdAuthenticationProvider.SampleAuth</value>
</property>
