[ https://issues.apache.org/jira/browse/SPARK-3600?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Xiangrui Meng updated SPARK-3600: - Description: RDD's classTag is not passed in through CacheManager. So RDD[Double] uses object arrays for caching, which leads to huge overhead. However, we need to send the classTag down many levels to make it work. (was: RandomDataGenerator doesn't have a classTag or @specilaized. So the generated RDDs are RDDs of objects, that cause huge storage overhead.) > RDD[Double] doesn't use primitive arrays for caching > > > Key: SPARK-3600 > URL: https://issues.apache.org/jira/browse/SPARK-3600 > Project: Spark > Issue Type: Bug > Components: MLlib >Affects Versions: 1.1.0 >Reporter: Xiangrui Meng >Assignee: Xiangrui Meng > > RDD's classTag is not passed in through CacheManager.
