Had a day long meeting with a Cloudera engineer ($400 an hour, we're in the wrong technology) and it turns out our production cluster was set up making the wrong choices at almost every decision point. Weeeeee!

Cloudera is absurdly over priced. I still don't really get how in this day and age people still pay companies like that ridiculous amounts of money.

Larry Ellison is being forced to take a pay cut so I guess that's a good sign

It's like crack. The documentation and community is good enough to get you so far but not to next level so at a certain point you have to pay for the expertise you haven't got.

In what way?

There are a number of companies out there that provide a lot for a lot cheaper. Granted, I'm biased given that I work at one of them...

C# / .NET experts,

I would be forever indebted to you if you can answer this SO question, which was posed by someone from a firm we outsource some things to, and is slowing down my development timeline. I know nothing about Microsoft server admin, which is what this involves:

http://stackoverflow.com/questions/1...ol-allow-heade

(and if you don't know the answer, an upvote would be appreciated on the chance it gets it some more attention)

Thanks guys!

EDIT: also, if you don't know the answer but have an idea where i could find someone who could help (i don't mind paying), that would be appreciated too.

I'm not entirely sure of the history, I'm new to the project and everyone that started the project no longer works for us. I don't know if we started with Cloudera or migrated to it at some point. Essentially our name node had been a data node in the past and was never cleaned up of old data. We're storing data on the / partition and used our standard RAID configuration of the discs combining several discs into a virtual bigger disc. Oh, and our file format is CSV and we're not using any compression. On the plus side, once we get the boxes rebuilt and configured properly we should see some big improvements in our run times...

If you use the cloud and s3 you avoid almost all of those problems.

Obviously I don't know all of your companies specific details so I realize I could be way off base here. But the majority of companies in your situation would be able to keep their data on S3 without any real negatives (and some big positives) and you'd be able to spin up fresh hadoop clusters on hardware just as you need them. If you don't have any big jobs you can save a bunch of money not running the cluster and if you have a really big job you can spin up a larger cluster just for that job.

You save money on hardware costs, licensing costs, and consulting costs.

Obvious downside/negative of s3 is that it's a US based company (that is known to comply with authorities). It's becoming surprisingly relevant over here especially since companies that tend to need something involving hadoop are also the ones that often have somewhat sensitive data they are worried about (or at the very least a big quantity of data).

Which makes me wonder along the same lines...is there a good non-US github clone for private repos?

I don't have a good handle on our data but I think the cost of moving the data in and out is prohibitive, particularly when we already manage a **** ton of servers in house. I'm not sure if there are privacy concerns, but wouldn't be surprised. Regardless, I have very little input into the design decisions of the nodes, my responsibility is getting operational experience to be able to backup the guy who runs the production job stream.

Fair enough, and I assumed that if you have a contract with Cloudera its a big enough company that any sort of significant change like moving data/servers to the cloud would be painful, long, and involve a lot of Management peeps.

Just saying because I found a ton of advice on SO that suggested server suggestions that would break security, which desrves a skeptical eye.

We're generating about 500k pages of pdfs a month that are being sent to a printer to give you an idea of data flow.

At the moment we've only paid Cloudera to come in and consult, we don't have a standing contract with them, we may go that way if business expands.

Even at 2 MB a page you're talking less than $100/month for storage costs.

Edit: Just to be clear, that's $100/month for each month of generated data.

There's also a typo - a single quote following x-user-session but I assume that's not in the actual code.

I thought you paid for getting data out more than for storage, the cluster is around 2TB of data to generate the above reports, which is still less than the cost of a server per month I suppose.

You do - but not for retrieving data on a machine in AWS land.

So if you're running your Hadoop cluster in AWS you can access all of your data for free. If you're actually sending all of that data somewhere its like $240 to retrieve 2TB of data. Like you said though, still pales in comparison to other costs.
