      Description

      If there is a mountPath conflict, the pod is created and repeats the following error messages and keep running. This should not keep running and we had better fail at Spark side.

      $ k get pod -l 'spark-role in (driver,executor)'
      NAME    READY   STATUS    RESTARTS   AGE
      tpcds   1/1     Running   0          14m
