[jira] [Commented] (SPARK-23130) Spark Thrift does not clean-up
temporary files (/tmp/*_resources and /tmp/hive/*.pipeout)
[ https://issues.apache.org/jira/browse/SPARK-23130?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16328568#comment-16328568 ]
Sean Roberts commented on SPARK-23130:
--------------------------------------
* SPARK-15401: Similar report for the "_resources" files
* HIVE-6091: Possibly a fix for the "pipeout" files
> Spark Thrift does not clean-up temporary files (/tmp/*_resources and /tmp/hive/*.pipeout)

> Key: SPARK-23130
> URL: https://issues.apache.org/jira/browse/SPARK-23130
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.6.3, 2.1.0, 2.2.0
> Environment: * Hadoop distributions: HDP 2.5 - 2.6.3.0
> * OS: Seen on SLES12, RHEL 7.3 & RHEL 7.4
> Reporter: Sean Roberts
> Priority: Major
>
> Spark Thrift is not cleaning up /tmp for files & directories named like:
> /tmp/hive/*.pipeout
> /tmp/*_resources
> There are such a large number that /tmp quickly runs out of inodes *causing the partition to be unusable and many services to crash*. This is even true when the only jobs submitted are routine service checks.
> Used `strace` to show that Spark Thrift is responsible:
> {code:java}
> strace.out.118864:04:53:49 open("/tmp/hive/55ad7fc1-f79a-4ad8-8e02-26bbeaa86bbc7288010135864174970.pipeout", O_RDWR|O_CREAT|O_EXCL, 0666) = 134
> strace.out.118864:04:53:49 mkdir("/tmp/b6dfbf9e-2f7c-4c25-95a1-73c44318ecf4_resources", 0777) = 0
> {code}
> *Those files were left behind, even days later.*
