[jira] [Commented] (SPARK-12095) Window function rowsBetween throws exception

["Tristan Reid (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-12095?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15082921#comment-15082921 ] 

Tristan Reid commented on SPARK-12095:
--------------------------------------

The SQL syntax doesn't appear to work at all. 
  `select rank() OVER (PARTITION BY c1 ORDER BY c2 ) as rank from tbl`

Is that the case?
