Apache Spark reassigned SPARK-9103: ----------------------------------- Assignee: (was: Apache Spark) > Tracking spark's memory usage > ----------------------------- > > Key: SPARK-9103 > URL: https://issues.apache.org/jira/browse/SPARK-9103 > Project: Spark > Issue Type: Umbrella > Components: Spark Core, Web UI > Reporter: Zhang, Liye > Attachments: Tracking Spark Memory Usage - Phase 1.pdf > > > Currently spark only provides little memory usage information (RDD cache on > webUI) for the executors. User have no idea on what is the memory consumption > when they are running spark applications with a lot of memory used in spark > executors. Especially when they encounter the OOM, it’s really hard to know > what is the cause of the problem. So it would be helpful to give out the > detail memory consumption information for each part of spark, so that user > can clearly have a picture of where the memory is exactly used. > The memory usage info to expose should include but not limited to shuffle, > cache, network, serializer, etc. > User can optionally choose to open this functionality since this is mainly > for debugging and tuning. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
