--------------------------------------------------------------------
I've also run into this issue. Trying to simply include logging and application
configuration using {{--files}}, but I suppose I'll have to include those in
the docker image instead until this issue gets fixed.
EDIT: I tried using the --jars option as well to include a logging config file
as well. Files included in this fashion should also be added to the classpath,
but that doesn't seem to be the case as well.

> Make spark.files available in driver with cluster deploy mode on kubernetes
> ---------------------------------------------------------------------------
>
> Key: SPARK-31726
> URL: https://issues.apache.org/jira/browse/SPARK-31726
> Project: Spark
> Issue Type: Improvement
> Components: Kubernetes, Spark Core
> Affects Versions: 3.0.0
> Reporter: koert kuipers
> Priority: Minor
>
> currently on yarn with cluster deploy mode --files makes the files available
> for driver and executors and also put them on classpath for driver and
> executors.
> on k8s with cluster deploy mode --files makes the files available on
> executors but they are not on classpath. it does not make the files available
> on driver and they are not on driver classpath.
> it would be nice if the k8s behavior was consistent with yarn, or at least
> makes the files available on driver. once the files are available there is a
> simple workaround to get them on classpath using
> spark.driver.extraClassPath="./"
> background:
> we recently started testing kubernetes for spark. our main platform is yarn
> on which we use client deploy mode. our first experience was that client
> deploy mode was difficult to use on k8s (we dont launch from inside a pod).
> so we switched to cluster deploy mode, which seems to behave well on k8s. but
> then we realized that our program rely on reading files on classpath
> (application.conf, log4j.properties etc.) that are on the client but now are
> no longer on the driver (since driver is no longer on client). an easy fix
> for this seems to be to ship the files using --files to make them available
> on driver, but we could not get this to work.
