Ben updated SPARK-38079:
------------------------
Description:
*The problem*
When you spark-submit to kubernetes in cluster-mode:
# Kubernetes creates the driver
# Kubernetes creates a configmap that the driver depends on
This is a race condition. If the configmap is not created quickly enough, then
the driver will fail to start up properly.
See [this stackoverflow post|https://stackoverflow.com/a/58508313] for an
alternate description of this problem.
*To Reproduce*
# Download spark 3.2.0 or 3.2.1 from [https://spark.apache.org/downloads.html]
# Create an image with
{code:java}
bin/docker-image-tool.sh{code}
# Spark submit one of the examples to some kubernetes instance
# Observe the race condition

To solve, I suggest that spark should wait for the configmap to exist before
proceeding.
