Peng Meng commented on SPARK-21476: ----------------------------------- Seems transform should use transformImpl but not use? > RandomForest classification model not using broadcast in transform > ------------------------------------------------------------------ > > Key: SPARK-21476 > URL: https://issues.apache.org/jira/browse/SPARK-21476 > Project: Spark > Issue Type: Bug > Components: ML > Affects Versions: 2.2.0 > Reporter: Saurabh Agrawal > > I notice significant task deserialization latency while running prediction > with pipelines using RandomForestClassificationModel. While digging into the > source, found that the transform method in RandomForestClassificationModel > binds to its parent ProbabilisticClassificationModel and the only concrete > definition that RandomForestClassificationModel provides and which is > actually used in transform is that of predictRaw. Broadcasting is not being > used in predictRaw. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
