> In a few hard-to-reproduce situations, we've seen a problem where the UGI login call
causes a failure to login exception with the following cause:
> Caused by: javax.security.auth.login.LoginException: unable to find 
> LoginModule class: org.apache.hadoop.security.UserGroupInformation 
> $HadoopLoginModule
> After a bunch of debugging, I determined that this happens when the login occurs in a
thread whose Context ClassLoader has been set to null.
