    [ https://issues.apache.org/jira/browse/SPARK-23213?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16339166#comment-16339166

Hyukjin Kwon commented on SPARK-23213:
--------------------------------------

I think we should rather leave this won't fix .. I don't think we should keep the compatibility
