--------------------------------------
[~rolandjohann], looks it's better to ask in mailing list before filing it as
an issue here
> properties file via SPARK_CONF_DIR and --properties-file prevents definition
> of own properties via secrets/own mounts

> Key: SPARK-28627
> URL: https://issues.apache.org/jira/browse/SPARK-28627
> Project: Spark
> Issue Type: Bug
> Components: Kubernetes
> Affects Versions: 2.4.3
> Reporter: Roland Johann
> Priority: Major
>
> K8S resource manager dumps the config map to
> /opt/spark/conf/spark-defaults.conf and passes it to spark submit twice:
> * via env var SPARK_CONF_DIR
> * argument --properties-file
> This prevents definition if user defined properties, such as from secrets -
> currently it seems to be the only possibility to define spark config
> properties from secrets but is locked currently.
> Is this implementation intent? If yes, what are the reasons behind this
> decision?
