I see three ways for data to get into the cluster:

Awesome, and it'd end up in the Hadoop cluster in a table? How...do we kick that off most easily?
Nono, I mean our specific web request stream. I don't think there's any way to piggyback onto that for arbitrary other services. This is not an option for you, it's just a way that data gets into the cluster, for completeness.
Second: what's best practices for this? What resources are available? If I'm starting a service on Labs that provides data to third-parties,
What exactly do you mean here? That's a loaded term and possibly against the labs privacy policy depending on what you mean.
An API, Dan ;)
Ok, so ... usage of the API is what you're after, I think piwik is probably the best solution.
It's not. I've used Piwik before many times and it's not what we're looking for. My question is "how do I get the request logs into HDFS?" Your answer is a piece of software that, last time I checked, required JS executed on the client machine and will put the data in yet another service that can't be tightly integrated with our dashboards in the same way.
We should have a way of doing this. If there is genuinely no way of getting requests from labs varnish instances into HDFS, we need to either (a) develop that or (b) stop using Labs for any kind of beta release.
what would analytics recommend my easiest path is to getting request logs into Hadoop?
Weighing everything on balance, right now I'd say adding your name to the piwik supporters. So far, off the top of my head, that list is:
- wikimedia store
- annual report
- the entire reading vertical
- russian wikimedia chapter (most likely all other chapters would chime
in supporting it)
- a bunch of labs projects (including wikimetrics, vital signs, various
dashboards, etc.)
How is piwik linked to Hadoop? I'm not asking "how do we visualise the data" I'm asking how we get it into the cluster in the first place.
I think for the most part, piwik would handle reporting and crunching numbers for you and get you some basic reports. But if we wanted to crunch tons of data, we could integrate it with hadoop somehow.
I'm kind of challenging IIDNHIHIDNH (If it did not happen in HDFS it did not happen).
