[jira] [Commented] (SPARK-10785) Scale QuantileDiscretizer using distributed binning

    [ https://issues.apache.org/jira/browse/SPARK-10785?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15184711#comment-15184711 ] 

Nick Pentreath commented on SPARK-10785:
----------------------------------------

Pending SPARK-13600, this would no longer be necessary, since we would be using the DataFrame {{approxQuantile}} function.
