From the Strata + Hadoop World website:
The best minds in data will gather in London on 5-7 May, 2015 for Strata + Hadoop World to learn, connect, and explore the complex issues and exciting opportunities brought to business by big data, data science, and pervasive computing.
O’Reilly and Cloudera have recently partnered to bring Hadoop World to all Strata Conferences worldwide. Doug Cutting, Cloudera's Chief Architect and founder of Apache Hadoop, joins Roger Magoulas and Alistair Croll as chairs of Strata + Hadoop World to help shape the content.
The future belongs to those who understand how to collect and use their data successfully. And that future happens at Strata + Hadoop World.
