Subject [jira] [Updated] (HIVE-13453) Support ORDER BY and windowing clause in partitioning clause with distinct function
Date Mon, 09 May 2016 15:44:12 GMT

     [ https://issues.apache.org/jira/browse/HIVE-13453?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Aihua Xu updated HIVE-13453:
----------------------------
    Attachment: HIVE-13453.2.patch

Patch-2: Many test case failures were caused by the changing of inputOI => outputOI in
merge function. Changed back to inputOI since the intermediate type matches inputOI, not outputOI.

> Support ORDER BY and windowing clause in partitioning clause with distinct function

> Current distinct function on partitioning doesn't support order by and windowing clause
due to performance reason. Explore an efficient way to support that.
