Incremental Updates

Hadoop and Hive are quickly evolving to outgrow previous limitations for integration and data access.
On the near-term development roadmap, we expect to see Hive supporting full CRUD operations (Insert, Select, Update, Delete). As we wait for these advancements, there is still a need to work with the current options—OVERWRITE or APPEND— for Hive table integration.

The OVERWRITE option requires moving the complete record set from source to Hadoop.…

Hadoop is a business-critical data platform at many of the world’s largest enterprises. These corporations require a layered security model focusing on four aspects of security: authentication, authorization, auditing, and data protection. Hortonworks continues to innovate in each of these areas, along with other members of the Apache open source community. In this blog, we will look at the authentication layer and how we can enforce strong authentication in HDP via Kerberos.…

Customers’ Hadoop Journey

We’ve all had two weeks to reflect on Hadoop Summit 2014. One of the biggest differences that stood out in this year’s Summit (as compared to Summit 2013) was the presence of large enterprise customers that are using Apache Hadoop as an important part of their modern data architectures.

Hadoop has gone beyond its original Yahoo use case—indexing the web via a nightly batch MapReduce process —and into the mainstream of daily data processing and analytics with real-time, online, interactive, and batch applications at many notable companies.…
