Stavros Kontopoulos updated SPARK-27872:
----------------------------------------
Description:
Driver and executors use different service accounts in case the driver has
provided by the user, other than the default:
[https://gist.github.com/skonto/9beb5afa2ec4659ba563cbb0a8b9c4dd]
This makes the executor pods fail when the user links a service account with a
secret:
[https://kubernetes.io/docs/tasks/configure-pod-container/configure-service-account/#add-imagepullsecrets-to-a-service-account]
as executors will not use the driver's service account and will not be able to
get the secret in order to pull the related image.
I am not sure what is the assumption here for using the default account for
executors, probably that this account is limited (executors dont create
resources)? This is an inconsistency that could be worked around with the pod
template feature in Spark 3.0.0 but it breaks pull secrets.
