How-to: Deploy a CDH Cluster in Skytap Cloud

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.

How Rapleaf Works Smarter with Cloudera

Because raising the visibility of Apache Hadoop use cases is so important, in this post we bring you a re-posted story about how and why Rapleaf, a marketing data company based in San Francisco, uses Cloudera Enterprise (CDH and Cloudera Manager).

Founded in 2006, Rapleaf’s mission is to make it incredibly easy for marketers to access the data they need so they can personalize content for their customers. Rapleaf helps clients “fill in the blanks” about their customers by taking contact lists and, in real time, providing supplemental data points, statistics and aggregate charts and graphs that are guaranteed to have greater than 90% accuracy. Rapleaf is powered by Cloudera.

Business Challenges Before Cloudera

New: Cloudera Manager Free Edition Demo VM

With the availability of this new demo VM containing Cloudera Manager Free Edition and CDH4.1.2 on CentOS 6.2, getting quick hands-on experience with a freeze-dried single-node Apache Hadoop cluster is just a few minutes away after the download process. 

This new addition to our growing Demo VM menagerie is available, as usual, in VMware, VirtualBox, and KVM flavors. A 64-bit host OS is required.

Cloudera Manager 4.1 Now Available; Supports Impala Beta Release

I am very pleased to announce the availability of Cloudera Manager 4.1. This release adds support for the Cloudera Impala beta release, and management and monitoring of key CDH features.

Here are the highlights of Cloudera Manager 4.1:

Axemblr’s Java Client for the Cloudera Manager API

Axemblr, purveyors of a cloud-agnostic MapReduce Web Service, have recently announced the availability of an Apache-licensed Java Client for the Cloudera Manager API.

The task at hand, according to Axemblr, is to ”deploy Hadoop on Cloud with as little user interaction as possible. We have the code to provision the hosts but we still need to install and configure Hadoop on all nodes and make it so the user has a nice experience doing it.” And voila, the answer is Cloudera Manager, with the process made easy via the REST API introduced in Release 4.0.
