luyuan created SPARK-38425:
------------------------------
Summary: Avoid possible errors due to incorrect file size or type
supplied in spark conf.
Key: SPARK-38425
URL: https://issues.apache.org/jira/browse/SPARK-38425
Project: Spark
Issue Type: Improvement
Components: Kubernetes
Affects Versions: 3.2.1
Reporter: luyuan
This would avoid failures, in case the files are a bit large or a user places a
binary file inside the HADOOP_CONF_DIR.
Both of which are not supported at the moment.
The reason is, underlying etcd store does limit the size of each entry to only
1.5 MiB.

We can process this like SPARK-32221
