Providing Hadoop-as-a-Service to your internal users can be a major operational advantage.
Cloudera Director (free to download and use) is designed for easy, on-demand provisioning of Apache Hadoop clusters in Amazon Web Services (AWS) environments, with support for other cloud environments in the works. It allows for provisioning clusters in accordance with the Cloudera AWS Reference Architecture.
Cloudera Director 1.1 introduces new features and improvements that provide more options for creating and managing cloud deployments of Apache Hadoop. Here are details about how they work.
Cloudera Director, which was released in October of 2014, delivers production-ready, self-service interaction with Apache Hadoop clusters in cloud environments. You can find background information about Cloudera Director’s purpose and fundamental features in our earlier introductory blog post and technical overview blog post.
A new Spark tutorial and Trifacta deployment option make Cloudera Live even more useful for getting started with Apache Hadoop.
When it comes to learning Hadoop and CDH (Cloudera’s open source platform including Hadoop), there is no better place to start than Cloudera Live (cloudera.com/live). With a quick, one-button deployment option, Cloudera Live launches a four-node Cloudera cluster that you can learn and experiment in free for two-weeks. To help plan and extend the capabilities of your cluster, we also offer various partner deployments. Building on the addition of interactive tutorials and Tableau and Zoomdata integration, we have added a new tutorial on Apache Spark and a new Trifacta partner deployment.
Interested in Hive-on-Spark progress? This new AMI gives you a hands-on experience.
Nearly one year ago, the Apache Hadoop community began to embrace Apache Spark as a powerful batch-processing engine. Today, many organizations and projects are augmenting their Hadoop capabilities with Spark. As part of this shift, the Apache Hive community is working to add Spark as an execution engine for Hive. The Hive-on-Spark work is being tracked by HIVE-7292 which is one of the most popular JIRAs in the Hadoop ecosystem. Furthermore, three weeks ago, the Hive-on-Spark team offered the first demo of Hive on Spark.
With Cloudera Director, cloud deployments of Apache Hadoop are now as enterprise-ready as on-premise ones. Here’s the technology behind it.
As part of the recent Cloudera Enterprise 5.2 release, we unveiled Cloudera Director, a new product that delivers enterprise-class, self-service interaction with Hadoop clusters in cloud environments. (Cloudera Director is free to download and use, but commercial support requires a Cloudera Enterprise subscription.) It provides a centralized administrative view for cloud deployments and lets end users provision and scale clusters themselves using automated, repeatable, managed processes. To summarize, the same enterprise-grade capabilities that are available with on-premise deployments are now also available for cloud deployments. (For an overview of and motivation for Cloudera Director, please check out this blog post.)
The combination of OpenShift and Kite SDK turns out to be an effective one for developing and testing Apache Hadoop applications.
At Cloudera, our engineers develop a variety of applications on top of Hadoop to solve our own data needs (here and here). More recently, we’ve started to look at streamlining our development process by using a PaaS (Platform-as-a-Service) for some of these applications. Having single-click deployment and updates to consistent development environments lets us onboard new developers more quickly, and helps ensure that code is written and tested along patterns that will ensure high quality.
Cloudera Enterprise 5.2 contains new functionality for security, cloud deployments, and real-time architectures, and support for the latest open source component releases and partner technologies.
We’re pleased to announce the release of Cloudera Enterprise 5.2 (comprising CDH 5.2, Cloudera Manager 5.2, Cloudera Director 1.0, and Cloudera Navigator 2.1).

Apache Hadoop provides a great ecosystem of tools for extracting value from data in various formats and sizes. Originally focused on large-batch processing with tools like MapReduce, Apache Pig, and Apache Hive, Hadoop now provides many tools for running interactive queries on your data, such as Impala, Drill, and Presto. This post shows you how to use Amazon Elastic MapReduce (Amazon EMR) to analyze a data set available on Amazon Simple Storage Service (Amazon S3) and then use Tableau with Impala to visualize the data.
Using this new tutorial alongside Cloudera Live is now the fastest, easiest, and most hands-on way to get started with Hadoop.
At Cloudera, developer enablement is one of our most important objectives. One only has to look at examples from history (Java or SQL, for example) to know that knowledge fuels the ecosystem. That objective is what drives initiatives such as our community forums, the Cloudera QuickStart VM, and this blog itself.
Automating the creation of short-lived clusters for testing purposes frees our support engineers to spend more time on customer issues.
The first step for any support engineer is often to replicate the customer’s environment in order to identify the problem or issue. Given the complexity of Cloudera customer environments, reproducing a specific issue is often quite difficult, as a customer’s problem might only surface in an environment with specific versions of Cloudera Enterprise (CDH + Cloudera Manager), configuration settings, certain number of nodes, or the structure of the dataset itself. Even with Cloudera Manager’s awesome setup wizards, setting up Apache Hadoop can be quite time consuming, as the software was never designed with ephemeral clusters in mind.
