bq. It contains native executables.
So does Hive. Please look around.
bq. It contains native libraries.
So does Hive. Please look around.
bq. It contains jni libraries.
I'm not sure what makes this different from the previous two cases, but will
admit that you've got me there.
bq. Moving to Maven would be making it better in the opinion of the majority of
the development community.
So you have already conducted a poll? How large was your sample size and what
are the margins of error? Can you please publish the questions that were used?
Thanks.
bq. Certainly, I believe it is possible to make things worse with Maven.
How do we know that isn't going to happen here?
bq. I'm not a fan of how the Hadoop mavenization was done...
In your opinion what did they do wrong? It's starting to sound like there's
more than a little room for error when transitioning a project over to Maven.
Maybe the Maven community would benefit from having a best practices document
that highlighted these potential pitfalls.
bq. ... and I deeply regret not taking the time to make it better as it went in.
It's not too late to fix it, right? You're a committer on that project, which
along with your extensive Maven knowledge puts you in an excellent position to
lead this effort.
bq. ... but it was still better than the ant + ivy + maven ant tasks that we
had ...
I think part of the problem with the original build was that you were using
three components (ant, ivy, maven ant tasks), when you only needed to use two
(ant, ivy). Our build, especially post-HCatalog merge, suffers from this same
problem. This ticket was originally filed to track the task of removing either
Ivy or maven ant asks, but was quickly hijacked by people intent on replacing
everything with Maven. Owen, would it be OK with you if we return to the
original focus of this ticket and resolve it before again considering your
proposal? This will also give you time to strengthen your argument by fixing
the bugs and design defects in Hadoop's Maven build.
bq. If it hadn't been, it would have been rejected.
I hope you're joking.
bq. That said, in my experience most projects are better off with Maven builds
than ant + ivy + maven ant tasks.
What characteristics define a project that falls into the latter category, or
did you mean to say *all* instead of *most*?

> Reporter: Travis Crawford
> Assignee: Carl Steinbach

> Both Hive and HCatalog use ant as their build tool. However, Hive uses ivy
> for dependency resolution while HCatalog uses maven-ant-tasks. With the
> project merge we should converge on a single tool for dependency resolution.
