Subject [jira] [Commented] (HIVE-9534) incorrect result set for query that projects a windowed aggregate
Date Sun, 26 Apr 2015 11:25:38 GMT

    [ https://issues.apache.org/jira/browse/HIVE-9534?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14512997#comment-14512997
] 

N Campbell commented on HIVE-9534:
----------------------------------

While Postgres may not support ISO-SQL syntax as shown other vendors do. That said, if the
engine does not attempt to support distinct aggregation then a parsing error should be thrown
-and- the documentation improved at

https://cwiki.apache.org/confluence/display/Hive/LanguageManual+WindowingAndAnalytics
