Earlier quoted context omitted.
Hadoop's whole appeal was it was cheap and scalable. Did it actually work without serious engineering teams maintaining each distribution? absolutely not. the hype was purely VC funded. fast forward 10 years and hadoop has basically been killed off by hosted storage services that are more expensive but 10000x easier to manage.
I'm not really familiar with this industry. Are these Hadoop clusters hosted locally by these businesses? And MapR et all were providing the software/consulting to help manage them? Then I'm guessing better cloud hosted options came out offering similar capabilities. If that's the case was it really a big surprise that "cloud" hosting would eat any self-hosted platform's lunch?
Now what the cloud offered was so much more compelling. You had per hour pricing on the order of $20 for a minimal cluster. You had unlimited autoscaling so you didn't have to do capacity planning and go through procurement processes to pre-order hardware/licenses. And of course you had unlimited, ultra-cheap storage courtesy of S3. And it also allowed each team to have their own mini-cluster instead of everyone relying on some giant one.
I don't think the recent explosion in Data Science would've happened without the cloud.
