Even web giants like Facebook and Yahoo generally aren’t dealing with big data
Even web giants like Facebook and Yahoo generally aren’t dealing with big data, and the application of Google-style tools is inappropriate.
Facebook and Yahoo run their own giant, in-house “clusters”—collections of powerful servers—for crunching data. The necessity of these clusters is one of the hallmarks of big data. After all, data isn’t all that “big” if you could chew through it on your PC at home. The necessity of breaking problems into many small parts, and processing each on a large array of computers, characterizes classic big data problems like Google’s need to compute the rank of every single web page on the planet.
But it appears that for both Facebook and Yahoo, those same clusters are unnecessary for many of the tasks which they’re handed.
I guess we need some sort of “big journalism” sooner rather than later.

What Open Source Hadoop Coming to Windows Means to IT
This will open up Hadoop to a large number of organizations that have no in- house Linux skills. Shaun Connolly, vice president of Corporate Strategy at Hortonworks, explains the thinking behind moving HDP to Windows in this way: “Essentially it’s a market-driven decision,” he says. “Hadoop is built for the scaleout commodity hardware market, and the commodity hardware market is 70% Windows by install base and expertise.”
Employees in Windows-only companies will be able to make use of Hadoop easily because Excel can be used as a business intelligence tool to view the results of Hadoop Big Data analysis (whether Hadoop is running on Windows or Linux). “Ideally we want Microsoft users to be oblivious to the fact that everything is coming from Hadoop,” says Connolly. “If end users can consume data without any learning curve, thanks to tools like Excel, then they get more value.”
Either the data or the logic above is not sound:
- those Windows machines that make up the 70% of the market are probably running Excel
- those 70% of the market Windows machines are not going to run Hadoop
Based on this sort of market-share decisions, tomorrow we should see Hadoop for iOS and Android and Nokia. Sometime soon Microsoft will release Excel for iOS and maybe Android.

Cloudera Announces Cloudera Developer Kit, Enabling Developers to Build Hadoop Apps Faster
I didn’t know what to think of this announcement after reading the WSJ title . After checking the project GitHub page, I still don’t know what to make of it.

Hadoop Drives Down Costs
Darryl K. Taft reporting the experience of using Hadoop at UC Irvine Medical Center:
Because they were bleeding money, the team wanted a cost-effective solution. “Our target was $500 per terabyte. We were at $100,000 per terabyte with the old system,” Peterson said. “With our Hadoop cluster, we’re now at $900 per terabyte.”
How are these costs calculated?
- Fixed costs: hardware, any one time licenses
- Recurring costs: hardware replacement, energy, HR
Is this all?

Impala 1.0 - That was fast
Cloudera announces Impala 1.0 GA release.
That was fast—I guess this is one of the (little) advantages of having Hortonworks working on Stinger, Pivotal on HAWQ, Qubole offering Hive, Pig and Sqoop as-a-Service

Hadoop Virtualization
Roberto V. Zicari interviewing Joe Russell1 about Hadoop virtualization with Serengeti:
A common misconception when virtualizing Hadoop clusters is that we decouple the data nodes from the physical infrastructure. This is not necessarily true. When users virtualize a Hadoop cluster using Project Serengeti, they separate data from compute while preserving data locality. By preserving data locality, we ensure that performance isn’t negatively impacted, or essentially making the infrastructure appear as static. Additionally, it creates true multi-tenancy within more layers of the Hadoop stack, not just the name node.
I’m not 100% sure I get this, but the way I explained it to myself to actually make sense this would mean that HDFS lives directly on the physical hardware and only the compute part is virtualized. Is that what he means?

A Value Definition of Big Data
Jim Walker:
Last year, Shaun Connolly, Hortonworks VP of Corporate Strategy came up with this definition…
Big Data = Transactions + Interactions + Observations.
Well, give me an example of any data system that doesn’t satisfy this definition.
Here’s my proposal for yet another definition of Big Data: a buzzword that we’ll never have a real definition so we’d be better moving over.

Project Savanna: Hadoop and OpenStack
Timothy Prickett Morgan for The Register about Project Savanna, a collaboration between Mirantis, Hortonworks, and Red Hat:
Batman and Robin. Peanut butter and chocolate. OpenStack and Hadoop. These are things that go together, with the latter pairing being something that commercial OpenStack distie Mirantis, commercial Hadoop distie Hortonworks, and commercial KVM and Linux distie (and soon to be OpenStack commercializer) Red Hat are putting together under a new OpenStack effort dubbed Project Savanna.
Hadoop is at the age where everyone tries to package it and claim they’ll be the Red Hat of the Hadoop ecosystem. I cannot really dot the i-s and cross the t-s, but my gut feeling is that right now all these are actually more similar to the attempts of bringing Linux to the desktop.
We know how successful these have been so far.

Boundary for Splunk app for correlating alerts
Alex Williams for TechCrunch:
Boundary‘s application performance monitoring technology is now integrated into Splunk‘s enterprise platform, providing a window into apps that increasingly are distributed across cloud and on-premise virtualized environments.
At first I thought this means Boundary will use Splunk as the backend for the data. But Boundary is a service so that’s not the case. Plus Splunk can already be used for network management and monitoring.
According to the post, “Splunk real-time alerts are tagged as annotations in Boundary’s time-series graphs. Customers can then correlate alerts against application flow and performance data.” So basically this is monitoring your monitoring system, right?

Project Falcon: Tackling Hadoop Data Lifecycle Management
Venkatesh Seetharam announcing a new Apache incubating project in the Hadoop ecosystem open sourced by InMobi and Hortonworks:
Today we are excited to see another example of the power of community at work as we highlight the newly approved Apache Software Foundation incubator project named Falcon. This incubation project was initiated by the team at InMobi together with engineers from Hortonworks. Falcon is useful to anyone building apps on Hadoop as it simplifies data management through the introduction of a data lifecycle management framework.
I think this diagram describes Project Falcon best:
✚ Was there any other project addressing this space?

3 Big Data Use Cases in Banking
An article on Sys-Con about 3 high level and generic use cases of Big Data in banking:
- Customer experience
- Risk management
- Operations optimization
The first and the third are common across multiple fields. Risk management is critical to banks’ core business and I assume this is the domain where most of the technology investment happens.

Storm and Hadoop: Convergence of Big-Data and Low-Latency Processing at Yahoo!
Andy Feng wrote a blog post on YDN blog about the data processing architecture at Yahoo! for delivering personalized content by analyzing billions of events for 700mil. users and 2.2bil content pieces every day using a combination of batch-processing (Hadoop) and stream-processing (Storm):
Enabling low-latency big-data processing is one of the primary design goals of Yahoo!’s next-generation big-data platform. While MapReduce is a key design pattern for batch processing, additional design patterns will be supported over time. Stream/micro-batch processing is one of design patterns applicable to many Yahoo! use cases. In Q1 2013, we added Storm as a new service to our big-data platform. Similar to how Hadoop provides a set of general primitives for doing batch processing, Storm provides a set of general primitives for stream/micro-batch processing.
✚ I don’t think I’ve seen the term micro-batch processing used before. Any ideas why using it as an alternative to the well established stream processing?
