7 big data tools to ditch in 2017

We’ve been on this big data adventure for a while. Not everything is still shiny and new anymore. In fact, some technologies may be holding you back. Remember, this is the fastest-moving area of enterprise tech — so much so that some software acts as a placeholder until better bits arrive.
