Alan Gates commented on HIVE-4266:
----------------------------------
bq. Aren't these same users going to have to re-test and re-deploy every
application when they bump the version number of their hcatalog dependency?
In my experience when you install a new Hadoop, Hive, or other tool version it
is usually placed on a test/dev cluster for a while and users are given a
chance to run on it, and once that proves out it is promoted to the production
cluster(s). There isn't usually a step to validate every application and
obviously no need to re-deploy applications. In this scenario users can retest
on their schedule and decide which applications are not crucial enough to
warrant the effort.
On the other hand if you tell users, "This is not backward compatible, you have
to rewrite all your programs and scripts" you are forcing them to rewrite,
retest, and re-deploy everything before they can deploy the new version. This
puts a big barrier to uptake of the new version in their way.
I am fine with setting a sunset for these shell classes. Two "major" releases
(ie Hive 0.13 or 0.14 depending on which release they go out with).
bq. I'm convinced that if we don't do this now it's never going to happen...
Since Ashutosh is managing this release I'll defer to him, but I am concerned
about stuffing something this large in at the last minute. I understand that
in software "deferred" is a synonym for "when hell freezes over", but I
honestly have the patch mostly done. The unit tests are passing. I don't have
the javadoc doing the right thing yet and I need to run the system tests
against both org.apache.hcatalog and org.apache.hive.hcatalog, which I'm
estimating will take me a few days assuming I find a few bugs.
