Configure HiveServer 2 to use Custom Authentication

Procedure

  1. 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;
}
    The SampleAuthenticator.java code has an example implementation that has stored usernames and passwords.
  2. Configure the following properties in the hive-site.xml file on each node where HiveServer2 is installed:
    Property Value
    hive.server2.authentication CUSTOM
    hive.server2.custom.authentication.class The authentication class name. For example, hive.server2.custom.authentication.class 
    <property>
<name>hive.server2.authentication</name>
<value>CUSTOM</value>
</property>

<property>
<name>hive.server2.custom.authentication.class</name>
<value>hive.test.SampleAuthenticator</value>
</property>
  3. Restart Hiveserver2 to apply the changes: 
    maprcli node services -name hs2 -action restart -nodes <comma separated list of nodes>
