@jinfengni Agree with Paul. The difference between NC_HIGH and NC_AT_END
for the DESC case. I checked that Drill uses NC_HIGH for sorting. Please, see
it at
[jira](https://issues.apache.org/jira/browse/DRILL-5326?focusedCommentId=15900411&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15900411),
since github doesn't show formatted code correctly in the comments.
