Holden Karau created SPARK-42361:
------------------------------------
Summary: Add an option to use external storage to distribute JAR
set in cluster mode on Kube
Key: SPARK-42361
URL: https://issues.apache.org/jira/browse/SPARK-42361
Project: Spark
Issue Type: Improvement
Components: Kubernetes
Affects Versions: 3.5.0
Reporter: Holden Karau
tl;dr – sometimes the driver can get overwhelmed serving the initial jar set.
You'll see a lot of "Executor fetching spark://.../....jar" and then connection
timed out.
On YARN the jars (in cluster mode) are cached in HDFS.
