Yinan Li commented on SPARK-24137: ---------------------------------- Yeah, {{LocalDirectoryMountConfigurationStep}} was missed in the upstream PRs. We probably should try to get it into 2.3.1. > [K8s] Mount temporary directories in emptydir volumes > ----------------------------------------------------- > > Key: SPARK-24137 > URL: https://issues.apache.org/jira/browse/SPARK-24137 > Project: Spark > Issue Type: Bug > Components: Kubernetes > Affects Versions: 2.3.0 > Reporter: Matt Cheah > Priority: Major > > Currently the Spark local directories do not get any volumes and volume > mounts, which means we're writing Spark shuffle and cache contents to the > file system mounted by Docker. This can be terribly inefficient. We should > use emptydir volumes for these directories instead for significant > performance improvements. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
