> Project: Slider
> Issue Type: Bug
> Components: test
> Affects Versions: Slider 0.92
> Reporter: Gyula Komlossi

> After a change in Hadoop's Configuration class (introduced parser
> restriction) majority of the integration tests started failing with an error
> message:
> *AssertionError: Auth User is not Kerberized <user> (auth:SIMPLE) -security
> has already been set up with the wrong authentication method. This can occur*
> *if* ** *a file system has already been created prior to the loading of the
> security configuration*
>
> It is most likely because of the early initialisation of the Hadoop
> configuration. The base class of the Slider integration tests loads the
> Slider client configuration (slider-client.xml) using Hadoop’s Configuration
> class, which contains a static initialiser block. When this block gets
> executed, the settings from the core-default.xml is loaded with SIMPLE
> authentication, but the core-site.xml containing Kerberos as authentication
> is not available on the classpath. During the load of the configuration files
> (because of the mentioned change above), Hadoop implicitly logs in the test
> user with SIMPLE authentication and later when the tests try to authenticate
> the same user with the Kerberos keytab it throws an error.
>
> The tests could be fixed by adding the actual *-site.xml files to the
> classpath in the pom.xml of slider-funtest (using
> <additionalClasspathElements> for the maven-failsafe-plugin).
