[jira] [Commented] (SPARK-9963) ML RandomForest cleanup: replace predictNodeIndex with predictImpl

    [ https://issues.apache.org/jira/browse/SPARK-9963?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14731462#comment-14731462 ] 

Joseph K. Bradley commented on SPARK-9963:
------------------------------------------

Sorry for the slow response! (I've been traveling.)  Option 2 sounds best.  It can resemble the current predictImpl, but can use the version of shouldGoLeft taking binned feature values.
