---------------------------------------
Summary: Spark jobs failing on latest versions of Kubernetes
(1.15.3, 1.14.6, 1,13.10)
Key: SPARK-28921
URL: https://issues.apache.org/jira/browse/SPARK-28921
Project: Spark
Issue Type: Bug
Components: Kubernetes
Affects Versions: 2.4.3
Reporter: Paul Schweigert
Spark jobs are failing on latest versions of Kubernetes when jobs attempt to
provision executor pods (jobs like Spark-Pi that do not launch executors run
without a problem):
Here's an example error message:
{code:java}

Looks like the issue is caused by the internal master Kubernetes url not having
the port specified:
[https://github.com/apache/spark/blob/master//resource-managers/kubernetes/core/src/main/scala/org/apache/spark/deploy/k8s/Constants.scala#L82:7]
Using the master with the port (443) seems to fix the problem.
