In my post about the BYOH market last October, I noted that increasing numbers of existing players are connecting their offerings to Apache Hadoop, even as upstarts enter their markets with a singular focus. And last month, I pointed out that Nick Heudecker and I detected a surprising lack of concern about security in a recent Hadoop webinar. Clearly, these two topics have an important intersection – both Hadoop specialists (including distribution vendors) and existing security vendors will need to expand their efforts to drive awareness if they are to capture an opportunity that is clearly going begging today. Security for big data will be a key issue in 2014 and beyond.
