Security is one of the biggest topics in Hadoop right now. Historically Hadoop has been a back-end system accessed only by a few specialists, but the clear trend is for companies to put data from Hadoop clusters in the hands of analysts, marketers, product managers or call center employees whose numbers could be in the hundreds or thousands. Data security and privacy controls are necessary before this transformation can occur. HDP2, through the next release of Apache Hive introduces a very important new security feature that allows you to encrypt the traffic that flows between Hadoop and popular analytics tools like Microstrategy, Tableau, Excel and others.…

In this post, Gil Allouche of Qubole takes us from the basics of Hive through to getting started with more advanced uses, which we’ve compiled into another cheat sheet you can download here.…

He loves me, he loves me not… using daisies to figure out someone’s feelings is so last century. A much better way to determine whether someone likes you, your product or your company is to do some analysis on Twitter feeds to get better data on what the public is saying. But how do you take thousands of tweets and process them?  We show you how in our video – Understand your customers’ sentiments with Social Media Data – that you can capture a Twitter stream to do Sentiment Analysis.…

If you are an enterprise, chances are you use SAP.  And you are also more than likely using – or planning to use – Hadoop in your data architecture.

Today, we are delighted to announce the next step in our strategic relationship with SAP as they announce a reseller agreement with Hortonworks.  Under this agreement, SAP will resell Hortonworks Data Platform and provide enterprise support for their global customer base.  This will enable SAP customers to implement a data architecture that includes SAP HANA and the Hortonworks Data Platform and in so doing leverage existing skills to take advantage of the massive scalability and performance offered by Apache Hadoop.…

Over to Tanya…

I’d like to share some thoughts on the recent news that Eric Baldeschwieler has decided to leave Hortonworks. I’d like to start off first by thanking Eric for his contributions to the Hadoop community since its inception over 7 years ago, and I’d like to express my personal appreciation for his help in getting Hortonworks off the ground.

It’s hard to believe it’s been over two years since Hortonworks was founded by over 20 engineers from the original Yahoo!…
