[jira] [Commented] (SPARK-22493) sql null checks for Double.NaN do
not work
[ https://issues.apache.org/jira/browse/SPARK-22493?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16247660#comment-16247660 ]
Marco Gaido commented on SPARK-22493:
-------------------------------------
`NaN` is not `null`. They are different things. If you want to filter `NaN` you can use the SQL function `isnan`.
