------------------------------------
[~jiangjianfei] How about IBM Java version detection to make decision which
security class to use? I believe that was the approach taken by existing
developers.
> Can not find login module class for IBM due to hard codes

> Project: Hadoop Common
> Issue Type: Bug
> Components: security
> Affects Versions: 3.0.3
> Reporter: Jianfei Jiang
> Priority: Major

>
> 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?
