Xiangrui Meng resolved SPARK-6717. ---------------------------------- Resolution: Fixed Fix Version/s: 2.0.0 Issue resolved by pull request 11919 [https://github.com/apache/spark/pull/11919] > Clear shuffle files after checkpointing in ALS > ---------------------------------------------- > > Key: SPARK-6717 > URL: https://issues.apache.org/jira/browse/SPARK-6717 > Project: Spark > Issue Type: Improvement > Components: MLlib > Affects Versions: 1.4.0 > Reporter: Xiangrui Meng > Assignee: holdenk > Labels: als > Fix For: 2.0.0 > > > In ALS iterations, we checkpoint RDDs to cut lineage and to reduce shuffle > files. However, whether to clean shuffle files depends on the system GC, > which may not be triggered in ALS iterations. So after checkpointing, before > we let the RDD object go out of scope, we should clean its shuffle > dependencies explicitly. This function could either stay inside ALS or go to > Core. > Without this feature, we can call System.gc() periodically to clean shuffle > files of RDDs that went out of scope. -- 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
