fengchaoge commented on SPARK-26570: ------------------------------------ hello, [~deshanxiao] [~srowen] spark2.4.3 may also have the same problems. Our sql program runs stably on spark2.1.0, generating about 70,000 tasks . After migrating to spark2.4.3, the memory overflows directly. Driver logs like this:java.lang.OutOfMemoryError: GC overhead limit exceeded. The jstack log is shown below, may be all serializable file statuses collected. _!image-2019-10-13-18-41-22-090.png!_ !image-2019-10-13-18-45-33-770.png! > Out of memory when InMemoryFileIndex bulkListLeafFiles > ------------------------------------------------------ > > Key: SPARK-26570 > URL: https://issues.apache.org/jira/browse/SPARK-26570 > Project: Spark > Issue Type: Bug > Components: SQL > Affects Versions: 2.3.2 > Reporter: deshanxiao > Priority: Major > Attachments: image-2019-10-13-18-41-22-090.png, screenshot-1.png > > > The *bulkListLeafFiles* will collect all filestatus in memory for every query > which may cause the oom of driver. I use the spark 2.3.2 meeting with the > problem. Maybe the latest one also exists the problem. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
