["Edward Capriolo (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-3125?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13294463#comment-13294463 ] 

Edward Capriolo commented on HIVE-3125:
---------------------------------------

Nice catch. A feature that sorts out literals only is not useful outside of the unit tests. I will look at this.

> The sort_array function doesn't work against data that's actually come out of a table. The test suite only covers constants given in the query.
> If you try and use sort_array on an array from a table, then you get a ClassCastException that you can't convert LazyX to Comparable.
