I thought I'd check in.
After some encouragement from this group, I found some time and now have an
Accumulo client running in OSGi (Felix). It's rather primitive, at this
juncture, in that it is little more than a wrap job. I was, however,
forced to hack Zookeeper to get things to work.
Geoffry,
Fixing our logging libraries is an open issue -
https://issues.apache.org/jira/browse/ACCUMULO-1242
I hope to see it resolved soon. It's a pretty big task, so if you feel
inspired to help, it would be appreciated as well!
Thanks,
Mike

yes, there are also some bits using commons-logging. I think we managed to
scrub out java.util.logging.

If I were to pitch in on this, how would it work? and what logger? Do I
submit patches? Is slf4j the target?

I'd love to see us move to slf4j. Hadoop is in the middle of a proposal
about this too which sounds good to me.

I might be interested in taking on the work. Can you help me find your
patch?
I have a code base already in OSGi that works with MongoDB. I need to
point it at Accumulo instead, and if I can do so without porting out of
OSGi that would be nice.
You say the community would be well-accepting of
Geoffry,
As Josh pointed out, you should only need the Hadoop libraries on the
client side to use the Text object. This means you won't have to go through
the pain of placing the xml files in your root bundles.
Did you try the JAAS export from the packages in your container? Did that
help?

Corey,
Interesting you have Hadoop working in Karaf. I'm using equinox. It also
sounds as if I don't need to access HFDS in order to get Accumulo to work
in OSGi. If I understand you correctly, I only need have Text available.
I'll look into that. It does answer my question and maybe I can
Geoffry,

Sure, but are we talking Karaf-specific features here? You just want a
Hadoop Client bundle that works, right? The author of the Karaf-Hadoop
project already worked through the classpath issues so it's not a bad
starting
Thanks Corey,
I appreciate your insights wrt the internal nature of the Hadoop Client. I
hadn't yet opened it up. Ideally, we should be able to use these things as
black boxes, or so the theory goes. Nevertheless, I'll look into your notes.
My original question remains: Is the Accumulo Client
Ahh, let me try and address where I might have gone off the linguistic
reservation.
bndtools -- is an eclipse plugin that is very helpful when developing OSGi
bundles. It does a lot of grimy, boilerplate things for you.
inlining -- is where one places dependent *.jar files inside the OSGi
All,
To what extent does the Accumulo Client rely on the Hadoop Client? I
apologize if the question is a bit obtuse. But I got into dependency weeds
trying to get the Hadoop Client to work in OSGI. (See below Hadoop Client
woes) I am now wondering if I OSGified Accumulo's client would I
Geoffrey,
My quick answer is that I needed to adjust my container (Karaf in my case)
to export the JAAS packages because they come in the JRE. Then I needed to
make the hadoop bundle import them.
Also before I forget, Hadoop packages its default xml configurations
(core-site.xml,
Thank you Corey,
I was unaware of the service mix Hadoop client. It's funny that no one on
the Hadoop list ever mentioned it.
You say you have 1.4 working in OSGi. Did you do a proper port or just wrap
it with something like bnd? I have Hadoop 2.3.0 so I need to use Accumulo
1.5.1. I'm glad

Corey has made a ticket[1] for Accumulo 1.7.0. Not sure if he's planning
to do the work or if he just wanted to get it down on paper.
There's also been work done[2] to make sure the Accumulo client cleans
up after itself (or at least you have the ability to force a clean up).
That will help
Geoffry,
What OSGi container are you using currently? The servicemix Hadoop bundle
should get you going with the Hadoop client dependencies at least [1]. It
looks like one of the servicemix guys created a Hadoop ticket for making
bundles of their jars as well [2], though it doesn't look like
