From this article:

However, Cukierski thinks that the use of big data has become too trendy. “The whole big data idea is really within a big hype cycle,” mainly driven by a particular software framework for dealing with information, called Hadoop. “It’s not that Hadoop isn’t useful,” Cukierski says, but when companies look to it to solve small problems, “the people who are data scientists and actually statistically literate are kind of laughing, because you don’t need Hadoop to do most problems.”

Cheers.
