When it comes to security, what does it take to make Hadoop “enterprise ready?”
It may seem like a strange question because the open source Big Data processing system is clearly an enterprise tool. So why is it not yet enterprise ready?
The simple answer is that Hadoop, as it was first designed, was never intended to be used in the ways that it is used now. It was a straightforward tool for one person or a small group in an organization to run MapReduce jobs on large amounts of data. This data was siloed in the Hadoop cluster, and in that context only basic security was necessary.
