[jira] [Created] (SPARK-31302) Shared Volume Spark Kubernetes

Stefan Goldener created SPARK-31302:
---------------------------------------

             Summary: Shared Volume Spark Kubernetes
                 Key: SPARK-31302
                 URL: https://issues.apache.org/jira/browse/SPARK-31302
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 2.4.5
            Reporter: Stefan Goldener


Please change the deployment script for the workers to support one Shared Volume with the driver. E.g.:
https://kubernetes.io/docs/tasks/access-application-cluster/communicate-containers-same-pod-shared-volume/

Atm. If a driver runs in Kubernetes it is not possible to share a volume between the driver and the workers. 
Enabling a shared volume between Driver and Workers would allow the use of sc.textFile(file:///path/file.txt) to be used without any need of HDFS or S3 Storage.
