Guidelines for Installing CDH Packages on Unsupported Operating Systems

Installing CDH on newer unsupported operating systems (such as Ubuntu 13.04 and later) can lead to conflicts. These guidelines will help you avoid them.

Some of the more recently released operating systems that bundle portions of the Apache Hadoop stack in their respective distro repositories can conflict with software from Cloudera repositories. Consequently, when you set up CDH for installation on such an OS, you may end up picking up packages with the same name from the OS’s distribution instead of Cloudera’s distribution. Package installation may succeed, but using the installed packages may lead to unforeseen errors. 

Inside Cloudera Director

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.)

Cloudera Enterprise 5.1 is Now Available

Cloudera Enterprise’s newest release contains important new security and performance features, and offers support for the latest innovations in the open source platform.

We’re pleased to announce the release of Cloudera Enterprise 5.1 (comprising CDH 5.1, Cloudera Manager 5.1, and Cloudera Navigator 2.0).

How-to: Install a Virtual Apache Hadoop Cluster with Vagrant and Cloudera Manager

It’s been a while since we provided a how-to for this purpose. Thanks, Daan Debie (@DaanDebie), for allowing us to re-publish the instructions below (for CDH 5)!

I recently started as a Big Data Engineer at The New Motion. While researching our best options for running an Apache Hadoop cluster, I wanted to try out some of the features available in the newest version of Cloudera’s Hadoop distribution: CDH 5. Of course I could’ve downloaded the QuickStart VM, but I rather wanted to run a virtual cluster, making use of the 16GB of RAM my shiny new 15″ Retina Macbook Pro has ;)

How-to: Easily Do Rolling Upgrades with Cloudera Manager

Unique across all options, Cloudera Manager makes it easy to do what would otherwise be a disruptive operation for operators and users.

For the increasing number of customers that rely on enterprise data hubs (EDHs) for business-critical applications, it is imperative to minimize or eliminate downtime — thus, Cloudera has focused intently on making software upgrades a routine, non-disruptive operation for EDH administrators and users.

Capacity Planning with Big Data and Cloudera Manager

Thanks to Bill Podell, VP Big Data and BI Practice, MBI Solutions, for the guest post below.

Capacity planning has long been a critical component of successful implementations for production systems. Today, Big Data calls for a particularly deep understanding of capacity management – because resource utilization explodes as business users, analysts, and data scientists jump onboard to analyze and use newly found data. The resource impact can escalate very quickly, causing poor loading and or response times. The result is throwing more hardware at the issue without any understanding of what impact the new hardware will have on the current issue. Better yet, be proactive and know about the problem before the problem even occurs!

How-to: Extend Cloudera Manager with Custom Service Descriptors

Thanks to Jonathan Natkins of WibiData for the post below about how his company extended Cloudera Manager to manage Kiji. Learn more about Kiji and the organizations using it to build real-time HBase applications at Kiji Sessions, happening on May 6, 2014, the day after HBaseCon.

As a partner of Cloudera, WibiData sees Cloudera Manager’s new extensibility framework as one of the most exciting parts of Cloudera Enterprise 5. Cloudera Manager 5.0.0 provides the single-pane view that Apache Hadoop administrators and operators want to effectively manage a cluster of machines. Additionally, Cloudera Manager now offers tight integration for partners to plug into the CDH ecosystem, which benefits Cloudera as well as WibiData.
