Description

User-specified secrets are mounted into both the main container and init-container (when it is used) in a Spark driver/executor pod, using the MountSecretsBootstrap. Because MountSecretsBootstrap always adds the secret volumes to the pod, the same secret volumes get added twice, one when mounting the secrets to the main container, and the other when mounting the secrets to the init-container. See https://github.com/apache-spark-on-k8s/spark/issues/594.
