[jira] Issue Comment Edited: (HIVE-1549) Add ANSI SQL correlation
aggregate function CORR(X,Y).
[ https://issues.apache.org/jira/browse/HIVE-1549?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12900450#action_12900450 ]

-----------------------------------------------------------
Hmmm, looking more closely...your patch includes changes to udaf_covar_pop.q.out and covar_samp.q.out (and those include conflict markers, which should never be there in a submitted patch). But this change shouldn't actually affect those files at all, right? I think if you just revert those before svn diff, all should be well.
