vote for a release candidate
I have created a release candidate for Hive.
https://svn.apache.org/repos/asf/hadoop/hive/tags/release-0.4.0-rc0/
Let me know if it is OK to publish this release candidate.
Thanks,
-namit

Just replied on the JIRA. Is this really a regression - the code in 0.3.0 and 0.4.0 seems similar...

I am not sure 718 is a valid requirement. I think it got in by legacy.
Should we even support LOAD INTO ?
We only support INSERT OVERWRITE, similarly, we should only support LOAD OVERWRITE INTO.
Is anyone using LOAD INTO without OVERWRITE ?
Thanks,

What do you guys think the feasibility of HIVE-718 being fixed for 0.4.0 is?
I think a completely correct solution is likely to be very tough to achieve,
but as is it's a regression from 0.3.0 in that the functionality silently
fails.

Clearly with the fix it is still dangerous for them to use LOAD INTO unless they understand the consistency implications or have put work arounds to address some reader crashes. I agree though that since this is a regression, we should get the functionality to what it was in 0.3

Hi Namit,
Yes, we have customers who are using LOAD INTO without OVERWRITE. The use case is for collecting session data into a table partitioned by the hour of session start time. Since sessions are of varying lengths, incremental loads are necessary as sessions finish up.
There are a couple of possible workarounds, but all of them have drawbacks.
