Exhibit 99.6

We’ve just announced that Cloudera and Hortonworks have agreed to merge to form a single company. I want to explain the thinking behind the deal and the combination. Rob Bearden from Hortonworks has written up a post sharing his thoughts, as well.

First, remember the history of Apache Hadoop.

Google built an innovative scale-out platform for data storage and analysis in the late 1990s and early 2000s, and published research papers about their work. Doug Cutting and Mike Cafarella were working together on a personal project, a web crawler, and read the Google papers. The two of them started the Hadoop project to build an open-source implementation of Google’s system.

Yahoo quickly recognized the promise of the project. It staffed up a team to drive Hadoop forward, and hired Doug. That team delivered the first production cluster in 2006 and continued to improve it in the years that followed.

In 2008, I co-founded Cloudera with folks from Google, Facebook and Yahoo to deliver a big data platform built on Hadoop to the enterprise market. We believed then, and we still believe today, that the rest of the world would need to capture, store, manage and analyze data at massive scale. We were the first company to commercialize the software, building on the work done at Yahoo and other consumer internet companies.

Three years later, the core team of developers working inside Yahoo on Hadoop spun out to found Hortonworks. They, too, saw the enormous potential for data at scale in the enterprise. They had proven their ability to build and deliver the technology at Yahoo.

Since 2011, our two companies have each innovated to build better products and win more business. In the competitive world of data management, we can each look with respect at the success of the other. I’m proud of what we’ve done at Cloudera, and I’m impressed at what the team has accomplished at Hortonworks.

Open source software has made the competitive dynamic more interesting than it is for most companies. While we’ve each worked hard to create differentiation, we share an enormous amount of code in our products. Our development teams have collaborated on the original Hadoop software, and on newer entrants to the ecosystem like Apache Hive, Apache Spark and more -- a large and growing collection of projects aimed at massive data storage and analysis.

In the years since Cloudera and Hortonworks started, the competitive landscape has changed tremendously. Today, the market includes a growing collection of companies who recognize what we both knew early -- big data is a big deal. In the data center and in the cloud, there’s a proliferation of players, often building on technology we’ve created or contributed to, battling for share.

The opportunity has only grown with the advent of practical Internet of Things applications. The tremendous growth in both unstructured and structured data overwhelms traditional data warehouses. Machine learning brings new challenges, but also transformative power, to our customers. We have each innovated separately in those areas. We are both convinced that a scale-out, shared-nothing architecture -- the foundation of Hadoop -- is essential for IoT, data warehousing and ML. We both plan to help enterprises embrace those capabilities.

Besides that, our enterprise customers want us to deliver projects like Apache Nifi, Apache Spark and Apache Impala in the data center and in the public cloud. Efforts like the Cloud Native Computing Foundation, and the embrace of containerization and orchestration in the Hadoop ecosystem, making the platform easier to use and simpler to operate, behind the firewall and in the cloud.

That’s a future we can pursue better together. We remain committed to open source. Within our increasingly competitive space, we can innovate more effectively together than we can alone, , collaborating in every way to deliver cloud-native products in the data center and in the public cloud, can continue to lead the market and innovate in the way we each have done independently for so long.

I couldn’t be more pleased about bringing these two companies together. Here’s what you can expect in the months to come.

We’re announcing the combination today, but we don’t expect the deal to close for several months. We’ll undergo the normal regulatory review that any merger of scale involving public companies gets, and the shareholders from both companies will have to meet and approve the deal.

Between now and the close date, we remain independent companies. Our customers are running our respective products. Our sales teams are working separate from each other with current and new customers to win more business and to make those customers successful. We’ll both continue to do that.

Customers who are running CDH, HDP and HDF are getting a new promise. Those product lines will each be supported and maintained for at least three years from the date our merger closes. Any customer who chooses either can be sure of a long-term future for the platform selected.

Our partners should find that the combination helps them, too. We each have large partner communities. Our partners will benefit from a single standard to build on, and a larger company with more customers to work with.

We have each recently made major new platform releases. Hortonworks version 3 and Cloudera version 6 both shipped this past summer. That turns out to be a fortunate coincidence.

We’ve both rebased our latest products on the current open source project releases, meaning our development lines are closer than they’ve been in some time. We expect to move quickly to combine the two into a single “unity” release at some point after we close the transaction.

Over the long term, we’ll enhance that single coherent platform to include all the features we each had developed separately, so that customers can safely upgrade from their current Hortonworks or Cloudera installations to the new product. Given our maintenance promise, those customers will be able to make that decision when it makes business sense. Their current workloads are safe.

In the meantime, each of us also has unique product offerings. Hortonworks offers its Hortonworks DataFlow, or HDF, product for streaming and IoT workloads. Cloudera offers the Cloudera Data Science Workbench (CDSW) and Workload Experience Manager (Workload XM). We’ll work quickly to cross-port those products so they work with both our respective platforms, so that current customers of either company have access to all the innovative products of both.

Both companies started because we believed deeply in the power of data. Since the very earliest days of Hadoop, we’ve worked -- separately, as companies, and together, in the open source community -- to prove that belief correct.

Together, we’ll accelerate innovation for our customers and the community. Working as one, we’ll extend the broad Hadoop ecosystem with containerization and orchestration, making it more elastic and more self-service. We are uniquely positioned to deliver the first enterprise data cloud, from the edge to AI.

Forward!
