Edwina Lu commented on SPARK-23429: ----------------------------------- [~assia6], it's being reviewed internally right now. I will post the PR when the review and any changes are done. > Add executor memory metrics to heartbeat and expose in executors REST API > ------------------------------------------------------------------------- > > Key: SPARK-23429 > URL: https://issues.apache.org/jira/browse/SPARK-23429 > Project: Spark > Issue Type: Sub-task > Components: Spark Core > Affects Versions: 2.2.1 > Reporter: Edwina Lu > Priority: Major > > Add new executor level memory metrics ( jvmUsedMemory, executionMemory, > storageMemory, and unifiedMemory), and expose these via the executors REST > API. This information will help provide insight into how executor and driver > JVM memory is used, and for the different memory regions. It can be used to > help determine good values for spark.executor.memory, spark.driver.memory, > spark.memory.fraction, and spark.memory.storageFraction. > Add an ExecutorMetrics class, with jvmUsedMemory, executionMemory, and > storageMemory. This will track the memory usage at the executor level. The > new ExecutorMetrics will be sent by executors to the driver as part of the > Heartbeat. A heartbeat will be added for the driver as well, to collect these > metrics for the driver. > Modify the EventLoggingListener to log ExecutorMetricsUpdate events if there > is a new peak value for one of the memory metrics for an executor and stage. > Only the ExecutorMetrics will be logged, and not the TaskMetrics, to minimize > additional logging. Analysis on a set of sample applications showed an > increase of 0.25% in the size of the Spark history log, with this approach. > Modify the AppStatusListener to collect snapshots of peak values for each > memory metric. Each snapshot has the time, jvmUsedMemory, executionMemory and > storageMemory, and list of active stages. > Add the new memory metrics (snapshots of peak values for each memory metric) > to the executors REST API. > This is a subtask for SPARK-23206. Please refer to the design doc for that > ticket for more details. -- 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
