The freedom to choose the on-premises or cloud environments for Hadoop that best meets the business needs is a critical requirement.” One of the choices in deploying Hadoop in the cloud environment is with Microsoft Azure using […]

Mayank Bansal, of EBay, is a guest contributing author of this collaborative blog. This is the 4th post in a series that explores the theme of enabling diverse workloads in YARN. See the introductory post to understand the context around all the new features for diverse workloads as part of Apache Hadoop YARN in HDP. Background  In Hadoop YARN’s […]

Introduction Multihoming is the practice of connecting a host to more than a single network. This is frequently used to provide network-level fault tolerance – if hosts are able to communicate on more than one network, the failure of one network will not render the hosts inaccessible. There are other use cases for multi-homing as […]

The components in a modern data architecture vary from one enterprise to the next and the mix changes over time. Many of our Hortonworks subscribers need support ensuring that their Hortonworks Data Platform (HDP) clusters are optimally configured. This means that they need proactive, intelligent cluster analysis. As businesses onboard new workloads to the platform, […]

Apache Hadoop has emerged as a critical data platform to deliver business insights hidden in big data. As a relatively new technology, system administrators hold Hadoop to higher security standards. There are several reasons for this scrutiny: External ecosystem that comprise of data repositories and operational systems that feed Hadoop deployments are highly dynamic and […]
