Grokbase Groups Hive dev October 2010
FAQ
At the Hive contributor meeting, we discussed this and came to the conclusion that the failures reported so far are ignorable based on the Hudson history (and in this case Ning's observation of JVM inconsistencies with respect to serialization format).

We need one more +1 from a committer before we can release.

I got the following test failures on the release candidate...

groupby2.q
groupby3.q
groupby4.q
groupby5.q
groupby6.q

not sure if this is just in my env or if others have seen this...

A sample of the diff is below and seems to be related to some plan ordering or some change in plan. Is anyone else getting this?

Yeah, the scripts should only be needed in configurations where JDO is told not to automatically update the schema. This is recommended for production environments.

For this particular release, taking a downtime while running the scripts is a good idea due to the nature of the changes (e.g. altering the primary key on COLS). That needn't be true in general for additive-only changes.

Carl did some sanity testing on it already, but any additional testing you can do before voting helps to ensure a quality release.

I am checking it out now. It seems like since i have used two trunk
versions since hive the view related tables have already been created.
I do not need the update script.
