What do you do at Cloudera?
Get started with Apache Hadoop and use-case examples online in just seconds.
Today, we announced Cloudera Live, a new online service for developers and analysts (currently in public beta) that makes it easy to learn, explore, and try out CDH, Cloudera’s open source software distribution containing Apache Hadoop and related projects. No downloads, no installations, no waiting — just point-and-play!
This FAQ contains answers to the most frequently asked questions about the architecture and configuration choices involved.
In December 2013, Cloudera and Amazon Web Services (AWS) announced a partnership to support Cloudera Enterprise on AWS infrastructure. Along with this announcement, we released a Deployment Reference Architecture Whitepaper. In this post, you’ll get answers to the most frequently asked questions about the architecture and the configuration choices that have been highlighted in that whitepaper.
Developers, rejoice: Impala is now available on EMR for testing and evaluation.
Very recently, Amazon Web Services announced support for running Cloudera Impala queries on its Elastic MapReduce (EMR) service. This is very good news for EMR users — as well as for users of other platforms interested in kicking Impala’s tires in a friction-free way. It’s also yet another sign that Impala is rapidly being adopted across the ecosystem as the gold standard for interactive SQL and BI queries on Apache Hadoop.
In this new installment of our “Meet the Project Founder” series, meet Tom White, founder of Apache Whirr, PMC Member for multiple other projects (Apache Hadoop, Apache Avro, Apache Bigtop, Apache Sqoop), and author of O’Reilly Media’s best-selling book, Hadoop: The Definitive Guide.
Editor’s Note (added Feb. 28, 2014): The instructions below are deprecated for Cloudera Manager releases beyond 4.5. Please refer to this doc for instructions pertaining to releases 4.6 and later.
Cloudera Manager includes a new express installation wizard for Amazon Web Services (AWS) EC2. Its goal is to enable Cloudera Manager users to provision CDH clusters and Cloudera Impala (the open source distributed query engine for Apache Hadoop) on EC2 as easily as possible (for testing and development purposes only, not supported for production workloads) - and thus is currently the fastest way to provision a Cloudera Manager-managed cluster in EC2.

Note: The post below is valid for Impala version 0.6 only and is not being maintained for subsequent releases. To deploy Impala 0.7 and later using a much easier (and also free) method, use this how-to.
You may have seen the recent announcement from Skytap about the availability of pre-configured CDH4 templates in the Skytap Cloud public template library. So for anyone who wants to try out a Cloudera Hadoop cluster—from small to large—it can now be easily accomplished in Skytap Cloud. The how-to below from Skytap’s Matt Sousely explains how.
The goal of this how-to will be to spin up a 10-node Cloudera Hadoop cluster in Skytap Cloud. To begin, let’s talk about the two new Cloudera Hadoop cluster templates. The first is Cloudera CDH4 Hadoop cluster: a 2-node Hadoop cluster template. It includes 2 nodes and a management node/server. The second is the Cloudera CDH4 Hadoop host template. This second template is not intended to run by itself in a configuration—rather, it contains a host VM that is ready to become another Hadoop node in the Cloudera CDH4 Hadoop cluster template-based configuration.

Today we bring you one user’s experience using Apache Whirr to spin up a CDH cluster in the cloud. This post was originally published here by George London (@rogueleaderr) based on his personal experiences; he has graciously allowed us to bring it to you here as well in a condensed form. (Note: the configuration described here is intended for learning/testing purposes only.)
Apache Whirr release 0.7.0 is now available. It includes changes covering over 50 issues, four of which were considered blockers. Whirr is a tool for quickly starting and managing clusters running on cloud services like Amazon EC2. This is the first Whirr release as a top level Apache project (previously releases were under the auspices of the Incubator). In addition to improving overall stability some of the highlights are described below:
