Sean Roberts created SPARK-23130: ------------------------------------ Summary: 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: 2.2.0, 2.1.0, 1.6.3 Environment: * OS: Seen on SLES12, RHEL 7.3 & RHEL 7.4 * Spark versions: 1.6.3, 2.1.0, 2.2.0 * Hadoop distributions: HDP 2.5 - 2.6.3.0 Reporter: Sean Roberts
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.* ** ---- Example files: {code:java} # stat /tmp/hive/55ad7fc1-f79a-4ad8-8e02-26bbeaa86bbc7288010135864174970.pipeout File: ‘/tmp/hive/55ad7fc1-f79a-4ad8-8e02-26bbeaa86bbc7288010135864174970.pipeout’ Size: 0 Blocks: 0 IO Block: 4096 regular empty file Device: fe09h/65033d Inode: 678 Links: 1 Access: (0644/-rw-r--r--) Uid: ( 1000/ hive) Gid: ( 1002/ hadoop) Access: 2017-12-19 04:53:49.126777260 -0600 Modify: 2017-12-19 04:53:49.126777260 -0600 Change: 2017-12-19 04:53:49.126777260 -0600 Birth: - # stat /tmp/b6dfbf9e-2f7c-4c25-95a1-73c44318ecf4_resources File: ‘/tmp/b6dfbf9e-2f7c-4c25-95a1-73c44318ecf4_resources’ Size: 4096 Blocks: 8 IO Block: 4096 directory Device: fe09h/65033d Inode: 668 Links: 2 Access: (0700/drwx------) Uid: ( 1000/ hive) Gid: ( 1002/ hadoop) Access: 2017-12-19 04:57:38.458937635 -0600 Modify: 2017-12-19 04:53:49.062777216 -0600 Change: 2017-12-19 04:53:49.066777218 -0600 Birth: - {code} Showing the large number: {code:java} # find /tmp/ -name '*_resources' | wc -l 68340 # find /tmp/hive -name "*.pipeout" | wc -l 51837 {code} -- 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
