Subject MiniCluster and "provided" scope dependencies
Date Tue, 24 Sep 2013 15:57:51 GMT
I'm curious to hear what people think on this.

I'm a really big fan of spinning up a minicluster instance to do some
"more real" testing of software as I write it.

With 1.5.0, it's a bit more painful because I have to add a bunch more
dependencies to my project (which previously would only have to depend
on the accumulo-minicluster artifact). The list includes, but is
likely not limited to, commons-io, commons-configuration,
hadoop-client, zookeeper, log4j, slf4j-api, slf4j-log4j12.

Best as I understand it, the intent of this was that Hadoop will
typically provide these artifacts at runtime, and therefore Accumulo
doesn't need to re-bundle them itself which I'd agree with (not
getting into that whole issue about the Hadoop "ecosystem"). However,
I would think that the minicluster should have non-provided scope
dependencies declared on these, as there is no Hadoop installation --
there's just the minicluster. As such, this would alleviate users from
having to dig into our dependency management or trial&error to figure
out what "extra" dependencies they have to include in their project to
actually make it work
