------------------------------------

             Summary: Spark does not use SessionManager
                 Key: SPARK-38693
                 URL: https://issues.apache.org/jira/browse/SPARK-38693
             Project: Spark
          Issue Type: Bug
          Components: Web UI
    Affects Versions: 3.2.1
            Reporter: Brad Solomon


Spark's failure to use a `SessionManager` causes `java.lang.IllegalStateException: No SessionManager` that prevents Spark UI from being used with [`org.keycloak.adapters.servlet.KeycloakOIDCFilter`](https://www.keycloak.org/docs/latest/securing_apps/#_servlet_filter_adapter) as the `spark.ui.filters` class.

 

Sample logs:

 

```

spark_1 | 22/03/29 18:43:24 INFO KeycloakDeployment: Loaded URLs from http://REDACTED/auth/realms/master/.well-known/openid-configuration
spark_1 | 22/03/29 18:43:24 WARN HttpChannel: /
spark_1 | java.lang.IllegalStateException: No SessionManager

```

 

Configuration:

 

```

spark.ui.filters=org.keycloak.adapters.servlet.KeycloakOIDCFilter
spark.acls.enable=true
spark.admin.acls=*
spark.ui.view.acls=*
spark.org.keycloak.adapters.servlet.KeycloakOIDCFilter.param.keycloak.config.file=/opt/bitnami/spark/conf/spark-keycloak.json

```

 

This exception emanates from Jetty:

 

[https://github.com/eclipse/jetty.project/blob/ae5c8e34e7dd4f5cce5f649e48469ba3bbc51d91/jetty-server/src/main/java/org/eclipse/jetty/server/Request.java#L1524]

 

It appears that Spark's `ServletContextHandler` has the ability to use a `SessionManager` but doesn't. This seems to be a blocker that prevents integration with Keycloak entirely.
