Questions about updated bundle\charms

[Cory Johns]

(note: cc'ing to the juju list in case anyone there also has any confusion
about these points)

Hey, Alex!  Welcome to the Big Data list.  Many apologies for not getting a
reply out to you sooner.

Both of those bundles should be functionally the same now, but the one in
the bigdata-dev namespace points to all of our in progress dev versions of
the charms and may be advanced with newer but still in testing features.
We plan to drop the separate namespace (with differing charm and bundle
revisions) in favor of the development channel feature once that is
complete, but my understanding is that may not be until Juju 2.1.  Still,
it will make things much less confusing once that is available.

I would definitely recommend sticking to the first one (
https://jujucharms.com/apache-hadoop-spark-zeppelin/) unless there is a
specific in-progress feature that you are wanting to test.

`juju quickstart` is the recommended way to deploy bundles in Juju 1.25.
However, it is a separate tool from Juju core, which is not an ideal
experience, and so is being folded in to the core Juju command in 2.0.  At
that point, you will deploy bundles in exactly the same way as charms:

    juju deploy apache-hadoop-spark-zeppelin

For the next couple of weeks, however, you will need juju-quickstart to
deploy the bundles, as documented on the charm store (
https://jujucharms.com/get-started):

    sudo apt-get install juju-quickstart
    juju quickstart apache-hadoop-spark-zeppelin

Regarding apache-hadoop-plugin, that service name actually did not change
with the recent update, so the bundles you referenced should work as they
are.

And you are absolutely correct that our big data contributing page (http://
bigdata.juju.solutions/getstarted) needs to be updated.  I will work on
that immediately.
