--------------------------------------
Summary: Slider functests are failing in Kerberized environment
Key: SLIDER-1262
URL: https://issues.apache.org/jira/browse/SLIDER-1262
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).
