Subject [jira] [Updated] (HIVE-4019) Ability to create and drop temporary partition function
Date Tue, 16 Apr 2013 20:59:16 GMT

     [ https://issues.apache.org/jira/browse/HIVE-4019?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Brock Noland updated HIVE-4019:
-------------------------------

    Attachment: HIVE-4019-1.patch

Hi guys,

I've rebased the original patch, attached. However, I am seeing a problem during compilation
because 
output column names is null on TableFunctionResolver. It seems this on purpose 
(See WIndowTableFunction) but I don't see any location to obtain the column names. 
RawInputColumnNames is also null. Any hints?


I have time to work on this tomorrow, but I don't want to hold up anything that is important
for
release so if this is holding anything up, please feel free to take it up.
