-----------------------------------------------------------------
I add a patch, it just make the value of os.login.module.name and
os.principal.class in class UserGroupInformation configurable.
However in class KerberosAuthenticator, it also have similiar codes and should
change to configurable, in this class, there is no given conf and cannot load
Configuration like UserGroupInformation do. One way to make the value in
KerberosAuthenticator is to set system environment, I dont think it is a good
approach. Any advice?

> As the differences between various versions of IBM, the login module class is
> sometimes different. However, the class for specified jdk (no matter the
> version) is hard coded in Hadoop code. We have faced the error like following:
> *javax.security.auth.login.LoginException: unable to find LoginModule class:
> com.ibm.security.auth.module.LinuxLoginModule*
>
> Should we set the value as a config which can be set by users?
