Describe the bug

We are attempting to use KeycloakOIDCFilter as our Apache Spark UI filter. However, we are struggling to configure the KeycloakOIDCFilter itself.

We have, in spark-defaults.conf:

spark.ui.filters=org.keycloak.adapters.servlet.KeycloakOIDCFilter

This is picked up successfully, and the Spark master logs show this filter being applied to all URL routes.

We have generated a client config file in the Keycloak Admin Console, which has spit out a keycloak-oidc.json.

But how do we tell KeycloakOIDCFilter about this information?

From the Spark docs

Filter parameters can also be specified in the configuration,
by setting config entries of the form spark.<class name of filter>.param.<param name>=<value>
For example:
spark.ui.filters=com.test.filter1
spark.com.test.filter1.param.name1=foo
spark.com.test.filter1.param.name2=bar

In our case that would seem to be:

spark.org.keycloak.adapters.servlet.KeycloakOIDCFilter.param.<name>=<value>

However, the KeycloakOIDCFilter Java class has only two constructors. One takes no parameters at all and one takes a KeycloakConfigResolver.

The Keycloak Java servlet filter adapter docs only talk about web.xml which isn't applicable in the case of configuring Spark.

So how can we properly configure/point to parameters for the KeycloakOIDCFilter servlet filter?
