The post you originally replied to listed specific technologies that purely add complexity when introduced to a project. Hadoop isn't replacing something equally complex, it's simply adding complexity. Now if you simply can't do with anything else, and you're at the point of rolling your own distributed filesystem and job scheduler and zookeeper and all the rest of it, then sure, try Hadoop, but that's not what we're talking about. Note that I can pick on Hadoop because the hype cycle has peaked there, but this applies to plenty of newer techs where it hasn't. You literally can get more of all the good things in my list by removing unnecessary complexity from a project. And yes, there really are some technologies that, most of the time you see it being used, the entire project would literally be better off with literally nothing in place of it. And yes, people still prefer to use the trendy thing.
