Doing DevOps with Cloudera Manager

More and more customers are using automation/configuration management frameworks alongside Cloudera Manager.

As Apache Hadoop clusters continue to grow in size, complexity, and business importance as the foundational infrastructure for an Enterprise Data Hub, the use cases for a robust and mature management console expand. 

What’s New in Cloudera Manager 5?

Learn the new features and enhancements in Cloudera Manager 5, including support for YARN, management of third-party apps and frameworks, and more.

The response to the Oct. 2013 release of Cloudera Enterprise 5 Beta has been overwhelming, and Cloudera is busily working closely with several customers to incorporate their feedback.

Things For Which We Are Thankful

Some things for which we are thankful, the 2013 edition (not listed in order):

1. The entire Apache Hadoop community for its constant and hard work to Make the Platform Better,

How-to: Add Cloudera Search to Your Cluster using Cloudera Manager

Cloudera Manager 4.7 added support for managing Cloudera Search 1.0. Thus Cloudera Manager users can easily deploy all components of Cloudera Search (including Apache Solr) and manage all related services, just like every other service included in CDH (Cloudera’s distribution of Apache Hadoop and related projects).

In this how-to, you will learn the steps involved in adding Cloudera Search to a Cloudera Enterprise (CDH + Cloudera Manager) cluster.

Installing the SOLR Parcel

Cloudera Enterprise 5 Beta is Now Available for Download

We are pleased to announce the beta release of Cloudera Enterprise 5 (CDH 5 and Cloudera Manager 5). This release has both Cloudera Impala and Cloudera Search integrated into CDH. It also includes many new features and updated component versions including the ones below:

Hadoop Administrator Training Gets Hands-On

I’ve always held a strong bias that education is most effective when the student learns by doing. As a developer of technical curricula, my goal is to have training participants engage with real and relevant problems as much as possible through hands-on exercises. The high rate at which Apache Hadoop is changing, both as a technology and as an ecosystem, makes developing Cloudera training courses not only demanding but also seriously fun and rewarding.

I recently undertook the challenge of upgrading the Cloudera Administrator Training for Apache Hadoop. I more than quadrupled the amount of hands-on exercises from the previous version, adding a full day to the course. At four days, it’s now the most thorough training for Hadoop administrators and truly the best way to start building expertise.

Cloudera Manager 4.7 Released

Cloudera Manager 4.7 is an update to Cloudera Manager 4 and contains a number of bug fixes and usability improvements. Furthermore, we have introduced new features such as:

How-to: Use Cloudera Enterprise with StackIQ

StackIQ takes a “software defined infrastructure” approach to provision and manage cluster infrastructure that sits below Big Data platforms such as Apache Hadoop. In the guest post below, StackIQ co-founder and VP Engineering Greg Bruno explains how to install Cloudera Enterprise on top of StackIQ’s management system so they can work together.

The hardware used for this deployment is a small cluster: one node (i.e. one server) for the StackIQ Cluster Manager and four nodes as backend/data nodes. Each node has two disks and all nodes are connected via 1Gb Ethernet on a Private Network. The Cluster Manager node is also connected to a Public Network using its second NIC. (StackIQ Cluster Manager is used in similar deployments between two nodes and 4,000+ nodes in size.)

How-to: Install Cloudera Manager and Cloudera Search with Ansible

The following guest post is re-published here courtesy of Gerd König, a System Engineer with YMC AG. Thanks, Gerd!

Cloudera Manager is a great tool to orchestrate your CDH-based Apache Hadoop cluster. You can use it from cluster installation, deploying configurations, restarting daemons to monitoring each cluster component. Starting with version 4.6, the manager supports the integration of Cloudera Search, which is currently in Beta state. In this post I’ll show you the required steps to set up a Hadoop cluster via Cloudera Manager and how to integrate Cloudera Search.

New E-Learning for Parcels

Cloudera’s new Parcels installation format has been released, and I’m excited to highlight just how useful (and mind-blowingly cool) it is to system administrators and anyone responsible for maintaining a CDH cluster.

If you haven’t read about or played with Parcels, they make components of the distribution significantly easier to manage, install, and upgrade. The new Parcel distribution format works with Cloudera Manager 4.5 and later. When you perform installations and upgrades using Parcels, you get access to new Cloudera Manager features such as:
