Title: Hadoop Data Lake Controversy: Can You Have Your Lake And Use It Too?


Hadoop provides an ideal platform for storing many types of data that business users - data engineers, data scientists, data analysts, and business analysts - can leverage for data science and analytics. But Hadoop is a file system that lacks the automation to catalog what data it contains, and has no native way for users to find and understand the data they need for their data science and analytics projects. The lack of automation is overlooked when a team conducts a pilot since the data set is known; however, it becomes debilitating as projects grow beyond a proof point or two. The end result is data anarchy where the business has to scavenge for data and hoard what it can find, while IT is desperately trying to manage the data to meet the needs of the business.

Using data in Hadoop is like scavenging at a flea market.  It is impossible to know upfront what data is there and it would take too much time to browse through the entire market. In the case of Hadoop, it is not practical to browse through all the files in the cluster to find the right ones to wrangle or visualize.

The opposite of shopping at a flea market is Amazon.com. From a user perspective, it is easy to search and find the right product very quickly. A user doesn’t need to write code or browse through endless list of items. Amazon.com provides a catalog of products with detailed information that anyone can use.

Waterline Data solves the challenges of finding, understanding, and governing data in Hadoop. Waterline Data is like Amazon.com for Hadoop data. Waterline helps anyone find and understand data in Hadoop without writing code or wasting time browsing through unintelligible files.  In addition to providing the self-service experience to find and understand the right data, Waterline Data also automates building and maintaining a data inventory, securely provisions data to users, and enables data governance throughout.
