hopper-signifyd opened a new pull request #28985: URL: https://github.com/apache/spark/pull/28985
### What changes were proposed in this pull request? This is a backport of changes from SPARK-25262, PR #22323 I plan to also backport SPARK-28042, PR #24879 after this is landed. That diff will also include a test confirming that related issue [SPARK-31666](https://issues.apache.org/jira/browse/SPARK-31666) is fixed. ### Why are the changes needed? Running Spark on Kubernetes and not being able to use mounted volumes as local storage causes issues that prevent Spark jobs from starting. I've seen this on AWS EKS, but I've been able to reproduce it with a basic spark-submit command on a standard K8S cluster. Upgrading to 3.0 just to fix this bug is more hassle than it's worth for some organizations. ### Does this PR introduce _any_ user-facing change? Technically, yes. This adds the spark.kubernetes.local.dirs.tmpfs back to Spark 2.4 from Spark 3. However, there's no "breaking changes" per se. ### How was this patch tested? The tests were backported. Also, we've been running our own custom Spark 2.4.5 build with this patch applied at my org for the past few months. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
