Zdenek Ott created HIVE-4778:
--------------------------------
Summary: hive.server2.authentication CUSTOM not working
Key: HIVE-4778
URL: https://issues.apache.org/jira/browse/HIVE-4778
Project: Hive
Issue Type: Bug
Components: Authentication
Affects Versions: 0.11.0
Environment: CentOS release 6.2 x86_64
java version "1.6.0_31"
Java(TM) SE Runtime Environment (build 1.6.0_31-b04)
Java HotSpot(TM) 64-Bit Server VM (build 20.6-b01, mixed mode)
Reporter: Zdenek Ott
I have created my own class PamAuthenticationProvider that implements
PasswdAuthenticationProvider interface. I have puted jar into hive lib
directory and have configured hive-site.xml in following way:
<property>
<name>hive.server2.authentication</name>
<value>CUSTOM</value>
</property>
<property>
<name>hive.server2.custom.authentication.class</name>
<value>com.avast.ff.hive.PamAuthenticationProvider</value>
</property>
I use SQuireL and jdbc drivers to connect to hive. During authentication Hive
throws following exception:
java.lang.RuntimeException: java.lang.NoSuchMethodException:

I have done small patch for
org.apache.hive.service.auth.CustomAuthenticationProviderImpl , that have
solved my problem, but I'm not sure if it's the best solution. Here is the
patch:
