---------------------------------------
Summary: Avoid failed mount warning from kubernetes and support
the "optional" mount.
Key: SPARK-30771
URL: https://issues.apache.org/jira/browse/SPARK-30771
Project: Spark
Issue Type: Bug
Components: Kubernetes
Affects Versions: 3.0.0
Reporter: Prashant Sharma
Attachments: Screenshot 2020-02-10 at 3.10.01 PM.png
1)https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.17/#configmapvolumesource-v1-core
Kubernetes allows an optional field indicating, that if the mount for this
config map fails, then it is not reattempted nor the pod is declared to be
failed.
In our current code base, we try to mount the volumes and create them later, it
works because, kubernetes reattempts failed mounting attempt, because the
`optional` field is `false` by default.
But, if this optional field is set to true, then that mount will not take place
at all. Because, when the mount is performed the volume is not created - so
mount fails. And this time the mount is not reattempted because the optional
field is set as true.
