Description

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: org.apache.hive.service.auth.PasswdAuthenticationProvider.<init>()

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:
