Breaking News: Cloudera Impala is Fast. Really Fast.

Editor’s note (added Feb. 2, 2014): You can review the latest (and exciting) Impala performance benchmark results by Cloudera here.

In the presentation below, Scott Leberknight of Near Infinity has done such a good and thorough job of dissecting Cloudera Impala, we want to share it with you here.

QuickStart VM: Now with Real-Time Big Data

For years, Cloudera has provided virtual machines that give you a working Apache Hadoop environment out-of-the-box. It’s the quickest way to learn and experiment with Hadoop right from your desktop.

We’re constantly updating and improving the QuickStart VM, and in the latest release there are two of Cloudera’s new products that give you easier and faster access to your data: Cloudera Search and Cloudera Impala. We’ve also added corresponding applications to Hue – an open source web-based interface for Hadoop, and the easiest way to interact with your data.

Make Hadoop Your Best Business Tool

Data analysts and business intelligence specialists have been at the heart of new trends driving business growth over the past decade, including log file and social media analytics. However, Big Data heretofore has been beyond the reach of analysts because traditional tools like relational databases don’t scale, and scalable systems like Apache Hadoop have historically required Java expertise. 

Configuring Impala and MapReduce for Multi-tenant Performance

Cloudera Impala has many exciting features, but one of the most impressive is the ability to analyze data in multiple formats, with no ETL needed, in HDFS and Apache HBase. Furthermore, you can use multiple frameworks, such as MapReduce and Impala, to analyze that same data. Consequently, Impala will often run side-by-side with MapReduce on the same physical hardware, with both supporting business-critical workloads. For such multi-tenant clusters, Impala and MapReduce both need to perform well despite potentially conflicting demands for cluster resources.

In this post, we’ll share our experiences configuring Impala and MapReduce for optimal multi-tenant performance. Our goal is to help users understand how to tune their multi-tenant clusters to meet production service level objectives (SLOs), and to contribute to the community some test methods and performance models that can be helpful beyond Cloudera.

Defining Realistic Test Scenarios

Cloudera Partners and Impala: Alteryx

Our thanks to Brian Dirking, Director of Product Marketing for Alteryx, for the guest post below:

At Alteryx we are excited about the release of Cloudera Impala. The impact on Big Data Analytics is that the ability to perform real-time queries on Apache Hadoop will provide faster access and results. This is applicable to our customers, the business users who are running analytics to get access to data, perform analytics, and then follow up with new questions. Insight doesn’t happen all at once. The ability to query and refine quickly is ultimately what will lead business users to insight.

Extending the Data Warehouse with Hadoop

“Are data warehouses becoming victims of their own success?”, Tony Baer asks in a recent blog post:

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.
