Hadoop Summit: Yahoo Gathers the Stuffed Elephant Crowd
3/28/2008
And that's where he expects other companies to jump on the Hadoop bandwagon.
"The data exploration is more generalizable to lots of businesses, and that's why we're seeing all this interest," he added. "Companies are amassing more and more data, and they need to explore it. The tools that are out there for doing ad hoc exploration and analysis of new data sets aren't as convenient."
Along with several Yahoo representatives, the roster of summit presenters included the IBM Almaden Research Center's Kevin Beyer, who described how to use JAQL, a query language for JSON (JavaScript Object Notation) data, in Hadoop apps.
Microsoft's Michael Isard was also on hand to talk about DryadLINQ, which combines Microsoft's Dryad distributed execution engine and the .NET Language Integrated Query (LINQ). DryadLINQ is similar to JAQL and Yahoo's open source Pig, which is an infrastructure designed to support ad hoc analysis of very large data sets. But DryadLINQ doesn't actually run on Hadoop.
"Microsoft is doing a very similar set of technologies," Cutting explained, "but all within Microsoft. They're not using an open source model, and it's not even a commercial product at this point. I think they're here because they want to talk with people on a technical level, and because this is important technology, but not in terms of actually cooperating with people by sharing code and building on one another's efforts."
Cutting named the framework "Hadoop" after his son's yellow stuffed elephant. The yellow pachyderm is the official mascot/logo of the project.
