-------------------------------------------

             Summary: Stop bundling dependencies in binary tarball
                 Key: ACCUMULO-4356
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-4356
             Project: Accumulo
          Issue Type: Improvement
          Components: build
            Reporter: Christopher Tubbs
            Assignee: Christopher Tubbs
             Fix For: 2.0.0


Currently, our binary tarball is built containing our own built jars, scripts, etc. as well
as some extra dependencies which we assume are not available in either the Hadoop lib directory
or the ZooKeeper lib directory.

These assumptions are tenuous, since we do not know what environment a user is going to be
running in, and which jars they already have installed on their system, provided by their
classpath or otherwise. Nor do we know whether the specific versions of the dependencies we're
bundling for the user are compatible with what they have on their system.

What we are trying to do is make things convenient for a user, by performing integration/packager/dependency
convergence tasks on behalf of the user... all based on poorly defined assumptions.

This bundling also adds an extra burden on us, as the upstream project, to maintain complex
LICENSE/NOTICE files for the bundled tarball artifact we produce, and it's *very* easy for
these legal files to unintentionally become out of sync when we change a version of a dependency
we are bundling.

We should not bundle any dependencies inside our binary tarball. For convenience, we can instead
provide a script which allows the user to easily download the dependencies we're currently
assuming they will need (the same ones we're currently packaging for them). This will provide
nearly the same convenience as we are currently providing, but in a way which does not require
burdensome maintenance on our LICENSE/NOTICE files, and in a way that the user could easily
customize this script to download the dependencies they actually need, if our assumptions
aren't valid for their environment.
