     [ https://issues.apache.org/jira/browse/SPARK-12769?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Reynold Xin closed SPARK-12769.
-------------------------------
    Resolution: Won't Fix

Closing as won't fix for now since doing this change would make the explain plan more confusing (if -> case).
