jlpedrosa commented on issue #24962: [SPARK-28149][K8S] Added variable to disable negative DNS caching URL: https://github.com/apache/spark/pull/24962#issuecomment-514609545 Hi @erikerlandson I'm not sure if I've explained myself. What I was trying to say is that spark (3.0/master) has capabilities to mount different types of volumes into the pods **without temaplates**. Using the args to spark submit: ``` spark.kubernetes.driver.volumes.[VolumeType].[VolumeName].mount.path Add the Kubernetes Volume named VolumeName of the VolumeType type to the driver pod on the path specified in the value. For example,spark.kubernetes.driver.volumes.persistentVolumeClaim.checkpointpvc.mount.path=/checkpoint. ``` That [VolumeType] can be only of the types I mentioned before (as in the doc). Then the question is, do you prefer to: - Improve args in spark submit so it can mount a configMap? - Mount the config map through templates? If we would extend the capabilities then it would be something like ``` spark-submit --spark.kubernetes.driver.volumes.configMap.myJavaSecOpts.mount.path=/opt/secopt --driver-java-options "-Djava.security.properties=/opt/secopt" ```
