"Hadoop is where science meets big data – it's the technical underpinning that powers our innovative consumer and advertiser products on the world's most-advanced digital canvas," says Blake Irving, Yahoo Executive Vice President and Chief Product Officer. "Yahoo!’s cloud and Hadoop make it possible for Yahoo! to rapidly personalize our content and advertising, and deliver highly relevant experiences, while maintaining the trust of our 600 million users."
Yahoo says Hadoop plays a key role in its home page, Yahoo Search, Yahoo Mail, and other properties.
"Businesses across all sectors are looking for ways to leverage the vast quantities of data they are accumulating, and Apache Hadoop is an efficient solution for processing data at scale," says Melanie Posey, research director at IDC Research. "Now organizations of various sizes can leverage Yahoo!'s Hadoop investment and deployments to run it on their own systems and build out their own Hadoop deployments without starting from scratch on internal science experiments."
Specifically, Yahoo announced the beta release of Hadoop with Security and Oozie, the company's workflow engine for Hadoop. This means enterprises will benefit from better controls for managing business-sensitive data, according to the company.

Google is sharing some interesting statistics on malware, such as the number of entries on the Google Safe Browsing Malware List that have occurred over the last twelve months, and search results containing a URL labeled as harmful.
“We’re glad to share this sort of data because we believe that collaboration and information sharing are crucial in driving anti-malware efforts forward,” says Niels Provos of Google’s Security Team.
Number of Entries on the Google Safe Browsing Malware List
“As we mentioned in our Top-10 Malware Sites blog post, we have seen a large increase in the number of compromised sites since April,” says Provos. “The number of entries on our malware list has more than doubled in one year, and we have seen periods in which 40,000 web sites were compromised per week. However, compared to infections associated with Gumblar and Martuz — two relatively large and well-known pieces of malicious code, many compromised web sites now point to hundreds of different domains.”
In January of last year, 1.2% of all Google search queries contained at least one such result. The trend has mostly been downward in the time that has passed since then, although you can see fluctuations.
Search Results Containing a URL Labeled as Harmful
Google says that as malware trends evolve, they’re constantly improving their systems to better detect compromised sites. The company notes that the increase in compromised sites they observed could partially be influenced by such improvements.
