[jira] [Commented] (SPARK-3967) Spark applications fail in yarn-cluster mode when the directories configured in yarn.nodemanager.local-dirs are located on different disks/partitions

["Josh Rosen (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-3967?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14238384#comment-14238384 ] 

Josh Rosen commented on SPARK-3967:
-----------------------------------

To give a quick update on this: I've merged [~preaudc]'s patch into {{master}} and {{branch-1.1}} (and will backport it into {{branch-1.2}} after the 1.2.0 release passes).

I'd also like to include [~rdub]'s patch, too, since it's a pretty good refactoring of this code.  That patch is getting a lot closer to merging; I'm going to try to loop back soon to provide more review feedback.

> Spark applications fail from time to time in yarn-cluster mode (but not in yarn-client mode) when yarn.nodemanager.local-dirs (Hadoop YARN config) is set to a comma-separated list of directories which are located on different disks/partitions.
> Steps to reproduce:
> 1. Set yarn.nodemanager.local-dirs (in yarn-site.xml) to a list of directories located on different partitions (the more you set, the more likely it will be to reproduce the bug):
> (...)
> <property>
>   <name>yarn.nodemanager.local-dirs</name>
>   <value>file:/d1/yarn/local/nm-local-dir,file:/d2/yarn/local/nm-local-dir,file:/d3/yarn/local/nm-local-dir,file:/d4/yarn/local/nm-local-dir,file:/d5/yarn/local/nm-local-dir,file:/d6/yarn/local/nm-local-dir,file:/d7/yarn/local/nm-local-dir</value>
> </property>
> (...)
> 2. Launch (several times) an application in yarn-cluster mode, it will fail (apparently randomly) from time to time
