Yahoo! girds Google's bastard grid child

Open sources Hadoop with Security

3 Big data security analytics techniques

Hadoop Summit Yahoo! has released a beta version of Hadoop with built-in security, while open sourcing the latest version of its in-house workflow engine for the Google-mimicking distributed number-crunching platform.

Speaking this morning at the Yahoo!-sponsored Hadoop Summit in Santa Clara, California, company Hadoop guru Eric Baldeschwieler said that both the Hadoop with Security beta and the Oozie workflow engine have been open sourced at Apache. The security beta has been deployed on the Hadoop clusters that Yahoo! maintains for research organizations, and Baldeschwieler tells The Reg that it is now part of Yahoo!'s Hadoop distro.

Based on Google’s (proprietary) software infrastructure, Hadoop is a means of crunching epic amounts of data across a network of distributed machines. Named for the stuffed elephant belonging to the son of project founder Doug Cutting, the open source platform now underpins online services operated by everyone from Yahoo! and Facebook and Twitter to — gasp! — Microsoft.

Hadoop duplicates GFS, Google's distributed file system, and MapReduce, Google's distributed number-crunching platform. In 2004, Google published a pair of research papers on these technologies, and Cutting used the papers to build a platform that would back Nutch, his open source web crawler. Hadoop was open sourced at Apache, and Yahoo! is still its largest contributor.

Hadoop with Security, Baldeschwieler says, integrates the platform with Kerberos, the open source authentication standard, while adding enhanced logging features. According to Baldeschwieler, the release is designed to allow the sharing of sensitive data with appropriate permissions and to "ease regulatory compliance". It's designed to prevent unauthorized access to data stored on Hadoop clusters, more effectively co-locate business sensitive data, and reduce costs by consolidating clusters.

Oozie — named with the Burmese term for, yes, elephant keeper — is designed for particularly complex workflows and data pipelines. At Yahoo! it's the de facto standard for ETL (extract, transform, and load) processing. This open source workflow engine is also part of the new Hadoop distro from startup Cloudera, released today.

Baldeschwieler tells The Reg that Yahoo! has been using Oozie for about six months. The version open sourced today is essentially Oozie 2.0. A 1.0 version was previously open sourced. ®
