[ https://issues.apache.org/jira/browse/SPARK-14283?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=15244568#comment-15244568 ] zhengruifeng commented on SPARK-14283: -- [~josephkb] I can work on this. There should be a version of randomSplit that avoid the local sort which is meaningless in ML. But the calls in ML should be add a extra param to avoid local sort IMO. > Avoid sort in randomSplit when possible > --- > > Key: SPARK-14283 > URL: https://issues.apache.org/jira/browse/SPARK-14283 > Project: Spark > Issue Type: Improvement > Components: SQL >Reporter: Joseph K.
