Dongjoon Hyun updated SPARK-27499: ---------------------------------- Affects Version/s: (was: 2.4.1) 3.0.0 > Support mapping spark.local.dir to hostPath volume > -------------------------------------------------- > > Key: SPARK-27499 > URL: https://issues.apache.org/jira/browse/SPARK-27499 > Project: Spark > Issue Type: Improvement > Components: Kubernetes > Affects Versions: 3.0.0 > Reporter: Junjie Chen > Priority: Minor > > Currently, the k8s executor builder mount spark.local.dir as emptyDir or > memory, it should satisfy some small workload, while in some heavily workload > like TPCDS, both of them can have some problem, such as pods are evicted due > to disk pressure when using emptyDir, and OOM when using tmpfs. > In particular on cloud environment, users may allocate cluster with minimum > configuration and add cloud storage when running workload. In this case, we > can specify multiple elastic storage as spark.local.dir to accelerate the > spilling. -- 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
