Subject Re: [VOTE] Apache Hive 0.13.1 Release Candidate 1
Date Thu, 15 May 2014 18:46:30 GMT
The apache dev list seems to still be a little wonky, Prasanth mailed
me saying he'd replied to this thread with the following content, that
I don't see in this thread:

"Hi Sushanth

https://issues.apache.org/jira/browse/HIVE-7067
This bug is critical as it returns wrong results for min(), max(),
join queries that uses date/timestamp columns from ORC table.
The reason for this issue is, for these datatypes ORC returns java
objects whereas for all other types ORC returns writables.
When get() is performed on their corresponding object inspectors,
writables return a new object where as java object returns reference.
This will cause issue when any operator perform comparison on
date/timestamp values (references will be overwritten with next
values).
More information is provided in the description of the jira.

I think the severity of this bug is critical and should be included as
part of 0.13.1. Can you please include this patch in RC2?”

I think this meets the bar for criticality(actual bug in core feature,
no workaround) and severity( incorrect results, effectively data
corruption when used as source for other data), and I'm willing to
spin an RC2 for this, but I would still like to follow the process I
set up for jira inclusion though, to make sure I'm not being biased
about this, so I would request two other +1s to champion this bug's
inclusion into the release.

Also, another thought here is whether it makes sense for us to try to
have a VOTE with a 72 hour deadline when the mailing list still seems
iffy and delaying mails by multiple hours. Any thoughts on how we
should proceed? (In case this mail goes out much later than I send it
out, I'm sending it out at 11:45AM PDT, Thu May 15 2014)
