How Impala Brings Real-Time, Big Data Analytics to Digital Reasoning’s Users

The following post, by Sarah Cannon of Digital Reasoning, was originally published in that company’s blog. Digital Reasoning has graciously permitted us to re-publish here for your convenience.

At the beginning of each release cycle, engineers at Digital Reasoning are given time to explore the latest in Big Data technologies, examining how the frequently changing landscape might be best adapted to serve our mission. As we sat down in the early stages of planning for Synthesys 3.8 one of the biggest issues we faced involved reconciling the tradeoff between flexibility and performance. How can users quickly and easily retrieve knowledge from Synthesys without being tied to one strict data model?

Why Apache Spark is a Crossover Hit for Data Scientists

Spark is a compelling multi-purpose platform for use cases that span investigative, as well as operational, analytics.

Data science is a broad church. I am a data scientist — or so I’ve been told — but what I do is actually quite different from what other “data scientists” do. For example, there are those practicing “investigative analytics” and those implementing “operational analytics.” (I’m in the second camp.)

Secrets of Cloudera Support: Inside Our Own Enterprise Data Hub

Cloudera’s own enterprise data hub is yielding great results for providing world-class customer support.

Here at Cloudera, we are constantly pushing the envelope to give our customers world-class support. One of the cornerstones of this effort is the Cloudera Support Interface (CSI), which we’ve described in prior blog posts (here and here). Through CSI, our support team is able to quickly reason about a customer’s environment, search for information related to a case currently being worked, and much more.

BinaryPig: Scalable Static Binary Analysis Over Hadoop

Our thanks to Telvis Calhoun, Zach Hanif, and Jason Trost of Endgame for the guest post below about their BinaryPig application for large-scale malware analysis on Apache Hadoop. Endgame uses data science to bring clarity to the digital domain, allowing its federal and commercial partners to sense, discover, and act in real time.

Email Indexing Using Cloudera Search and HBase

In my previous post you learned how to index email messages in batch mode, and in near real time, using Apache Flume with MorphlineSolrSink. In this post, you will learn how to index emails using Cloudera Search with Apache HBase and Lily HBase Indexer, maintained by NGDATA and Cloudera. (If you have not read the previous post, I recommend you do so for background before reading on.)

Which near-real-time method to choose, HBase Indexer or Flume MorphlineSolrSink, will depend entirely on your use case, but below are some things to consider when making that decision:

Customer Spotlight: Learn How Edo Closes the Advertising Loop with Hadoop at Cloudera Sessions Milwaukee

The Cloudera Sessions fall series is coming to a close next week, but first we’ll make a final stop in Milwaukee, Wisconsin (on Oct. 17), where attendees will hear about edo — a company that is revolutionizing the advertising space by closing the loop between promotions and point-of-sale transactions.

In Milwaukee, edo CTO Jeff Sippel will engage in a fireside chat with Cloudera’s VP of marketing, Alan Saldich. At edo, Jeff is responsible for the strategy, planning, and execution for the systems — including Apache Hadoop — that power the edo offer platforms.

Customer Spotlight: Persado Makes Marketing a Data Science

It’s common to hear people describe themselves as being “left-brained” or “right-brained” based on their tendency to be more logical and mathematically driven (left-brained), or, conversely, to be intuitive and creatively driven (right-brained). For example, people who prefer math over art are often considered left-brained. People who get a higher verbal score on their SATs than for math are often considered right-brained.

In general, language and creative writing are considered right-brained exercises. Many people also associate marketing and advertising as a right-brained function, whereas engineering is considered very left-brained.

Secrets of Cloudera Support: Impala and Search Make the Customer Experience Even Better

In December 2012, we described how an internal application built on CDH called Cloudera Support Interface (CSI), which drastically improves Cloudera’s ability to optimally support our customers, is a unique and instructive use case for Apache Hadoop. In this post, we’ll follow up by describing two new differentiating CSI capabilities that have made Cloudera Support yet more responsive for customers:

Email Indexing Using Cloudera Search

Why would any company be interested in searching through its vast trove of email? A better question is: Why wouldn’t everybody be interested? 

Email has become the most widespread method of communication we have, so there is much value to be extracted by making all emails searchable and readily available for further analysis. Some common use cases that involve email analysis are fraud detection, customer sentiment and churn, lawsuit prevention, and that’s just the tip of the iceberg. Each and every company can extract tremendous value based on its own business needs.
