Cloudera Impala and Partners: Tableau

Our thanks to Ted Wasserman, product manager for Tableau, for the guest post below:

Many of our customers are turning to Apache Hadoop as they grapple with their big data challenges. Hadoop offers many benefits such as its scalability, economics, and versatility. Even so, adoption-to-date has largely centered around applications with “batch”-oriented workloads because of the latency imposed by the MapReduce framework. To increase Hadoop’s usefulness and adoption in the business intelligence space where users need fast, interactive response times when they ask a question, a new approach was needed.

Cloudera Partners and Impala: Talend

Our thanks to Yves de Montcheuil, Vice President of Marketing for Talend, for the guest post below:

According to Wikipedia, the impala is a medium-sized African antelope; its name comes from the Zulu language meaning “gazelle”. Like elephants, it is found in savannas, and this may be the link with Hadoop. Impala is also the name of Cloudera’s SQL-on-Apache Hadoop project, launched in beta at Strata last October and just released in version 1.0.

Cloudera Partners and Impala: MicroStrategy

Our thanks to Kevin Spurway, Senior Vice President of Marketing for MicroStrategy Inc., for the guest post below:

Squeezing insight from Big Data isn’t easy. It’s a delicate balance between scalability, performance, and cost effectiveness across an entire architecture, spanning everything from data storage to mobile app consumption. That’s why MicroStrategy and Cloudera have been working closely together from a technology standpoint. And, that’s why we’re proud to stand as a launch partner, certifying the integration between Cloudera’s new Impala project and our core MicroStrategy enterprise analytics platform.

Impala is a giant step toward an era of highly cost-effective interactive analytics for Hadoop-based Big Data.

Customer Spotlight: Six3 Systems’ Wayne Wheeles Drives Cyber Security Innovation using Impala

This week represents quite a milestone for Cloudera and, at least we’d like to believe, the Hadoop ecosystem at large: the general availability release of Cloudera Impala. Since we launched the Impala beta program last fall, I’ve been fortunate enough to work with many of the 40+ early adopters who’ve been testing this near-real-time SQL-on-Hadoop engine in an effort to learn about their use cases and keep tabs on early experiences with the tool.

Customers running Impala today span a variety of industries, from large biotech company to online travel provider to digital advertiser to major financial institution, and each one has a unique use case for Impala. Stay tuned to learn more about their various use cases.

How the SAS and Cloudera Platforms Work Together

On Monday April 29, Cloudera announced a strategic alliance with SAS. As the industry leader in business analytics software, SAS brings a formidable toolset to bear on the problem of extracting business value from large volumes of data.

Over the past few months, Cloudera has been hard at work along with the SAS team to integrate a number of SAS products with Apache Hadoop, delivering the ability for our customers to use these tools in their interaction with data on the Cloudera platform. In this post, we will delve into the major mechanisms that are available for connecting SAS to CDH, Cloudera’s 100% open-source distribution including Hadoop.

Cloudera Impala 1.0: It’s Here, It’s Real, It’s Already the Standard for SQL on Hadoop

In October 2012, we introduced the Impala project, at that time the first known effort to bring a modern, open source, distributed SQL query engine to Apache Hadoop. Our release of source code and a beta implementation were met with widespread acclaim — and later inspired similar efforts across the industry that now measure themselves against the Impala standard.

Today, we are proud to announce the first production drop of Impala (download here), which reflects feedback from across the user community based on multiple types of real-world workloads. Just as a refresher, the main design principle behind Impala is complete integration with the Hadoop platform (jointly utilizing a single pool of storage, metadata model, security framework, and set of system resources). This integration allows Impala users to take advantage of the time-tested cost, flexibility, and scale advantages of Hadoop for interactive SQL queries, and makes SQL a first-class Hadoop citizen alongside MapReduce and other frameworks. The net result is that all your data becomes available for interactive analysis simultaneously with all other types of processing, with no ETL delays needed.

The Platform for Big Data is Here

It has been an exciting couple of days for new product announcements at Cloudera — exciting especially for me as the edges of the new platform for big data we have been talking about since Strata + Hadoop World 2012 come into focus.

Yesterday, Cloudera announced a strategic alliance with SAS. SAS is the industry leader in business analytics software, especially predictive analytics. Ninety percent of the Fortune 100 run SAS today. We have been working with SAS to make a number of its products work well with Cloudera including SAS Access, SAS Visual Analytics, and SAS High Performance Analytics (HPA). SAS HPA is an excellent case example of the future direction of Apache Hadoop as a data management platform:

Where to Find Cloudera Tech Talks Through June 2013

It’s time for me to give you a quarterly update (here’s the one for Q1) about where to find tech talks by Cloudera employees in 2013. Committers, contributors, and other engineers will travel to meetups and conferences near and far to do their part in the community to make Apache Hadoop a household word!

(Remember, we’re always ready to assist your meetup by providing speakers, sponsorships, and schwag.)

For a Limited Time: Live Impala Demo on EC2

As a follow-up to a previous post about the Impala demo he built during Data Hacking Day, Alan Gardner from Pythian has deployed the app for a limited time on Amazon EC2. We republish his original post below.

A little while ago I blogged about (and open sourced) a Cloudera Impala-powered soccer visualization demo, designed to demonstrate just how responsive Impala queries can be. Since not everyone has the time or resources to run the project themselves, we’ve decided to host it ourselves on an EC2 instance. [Note: instance live only for one week!] You can try the visualization; we’ve also opened up the Impala web interface, where you can see query profiles and performance numbers, and Hue (username and password are both ‘test’), where you can run your own queries on the dataset.

Deploying Impala on EC2

How-to: Create a CDH Cluster on Amazon EC2 via Cloudera Manager

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.
