------------------------------------
Summary: Add support for ESS in Spark sidecar
Key: SPARK-32642
URL: https://issues.apache.org/jira/browse/SPARK-32642
Project: Spark
Issue Type: Improvement
Components: Kubernetes
Affects Versions: 3.1.0
Reporter: Holden Karau
Assignee: Holden Karau
For Spark on Kubernetes there are multiple ways to achieve dynamic scaling.
Unlike in YARN mode ESS on Spark on K8s as a sidecar would not help with
dynamic scaling. Instead this helps with the situations where the executor JVM
may be overloaded or crash. If we do this as a sidecar we can share the same
mounts between the executor and the external shuffle storage.
