Apache Spark commented on SPARK-18553: -------------------------------------- User 'JoshRosen' has created a pull request for this issue: https://github.com/apache/spark/pull/16070 > Executor loss may cause TaskSetManager to be leaked > --------------------------------------------------- > > Key: SPARK-18553 > URL: https://issues.apache.org/jira/browse/SPARK-18553 > Project: Spark > Issue Type: Bug > Components: Scheduler > Affects Versions: 1.6.0, 2.0.0, 2.1.0 > Reporter: Josh Rosen > Assignee: Josh Rosen > Priority: Blocker > Fix For: 2.0.3, 2.1.0, 2.2.0 > > > Due to a bug in TaskSchedulerImpl, the complete sudden loss of an executor > may cause a TaskSetManager to be leaked, causing ShuffleDependencies and > other data structures to be kept alive indefinitely, leading to various types > of resource leaks (including shuffle file leaks). > In a nutshell, the problem is that TaskSchedulerImpl did not maintain its own > mapping from executorId to running task ids, leaving it unable to clean up > taskId to taskSetManager maps when an executor is totally lost. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
