Xiangrui Meng commented on SPARK-17822: --------------------------------------- I will take a look. > JVMObjectTracker.objMap may leak JVM objects > -------------------------------------------- > > Key: SPARK-17822 > URL: https://issues.apache.org/jira/browse/SPARK-17822 > Project: Spark > Issue Type: Bug > Components: SparkR > Reporter: Yin Huai > Attachments: screenshot-1.png > > > JVMObjectTracker.objMap is used to track JVM objects for SparkR. However, we > observed that JVM objects that are not used anymore are still trapped in this > map, which prevents those object get GCed. > Seems it makes sense to use weak reference (like persistentRdds in > SparkContext). -- 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
