Have you used Hadoop in production? Yes or no?

Have you used Hadoop to process 3D image files in production is a far more relevant question?

Even YouTube (Google) do not use Hadoop (map/reduce) for image processing. I'm simply countering your suggestion that Hadoop is a one-size-fits-all solution. It isn't. Hadoop is perfect for some things, but not the OPs task. It is all about choosing the right tool for the job.

I'd remind you that you didn't "bring Hadoop to the OPs attention". You responded to my post and told me about it. All I've done is respond to your more and more intransigent assertions. The only vanity being displayed here is yours.

    "I'm simply countering your suggestion that Hadoop is a one-size-fits-all solution."

    Oh i never said that. But since you did not answer "yes" nor "no" ... we can conclude that no, you have never used Hadoop in production.

    By the way ... did the OP ever specify exactly what kind of processing was needed? No. Not all image processing has to be CPU bound, after all. ;)

      And since you've completely failed to respond to any of the reasons why Hadoop is inappropriate for the task at hand we can conclude that you don't have a clue about image processing.

      Simply a case of the hammer wielder seeing everything as a nail. Last year it was "use a database"; this year "ooh, ooh, ooh, Hadoop" regardless of the problem, and next year it'll no doubt be Node:js.

        Just pointing out that you are rejecting technology unfairly. Without even having tried it. Which you have not, even though you tailor your language to imply that you have.
