As outlined at https://issues.apache.org/jira/browse/SPARK-38693 and https://stackoverflow.com/q/71667296/7954504, we are attempting to integrate Keycloak<https://www.keycloak.org/docs/latest/securing_apps/#_servlet_filter_adapter> Single Sign On with the Spark Web UI.
However, Spark errors out with: 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 This appears to be caused by Spark not using a Jetty SessionManager. (See the first link above for configuration of Spark.) Are there any workarounds to make this integration succeed, and if so, what would they look like? Would it be possible to use a Jetty Adapter<https://www.keycloak.org/docs/latest/securing_apps/#_jetty9_adapter> with Spark and if so, how?
