Hadoop has allowed us to move towards a unified source of truth for all of organization’s data. Managing data location, schema knowledge and evolution, fine-grained business rules based access control, and audit and compliance needs will become critical with increasing scale of operations.

In this talk, we will share an approach in tackling the above challenges. We will explain how to register existing HDFS files, provide broader but controlled access to data through a data discovery tool with schema browse and search functionality, and leverage existing Hadoop ecosystem components like Pig, Hive, HBase and Oozie to seamlessly share data across applications. Integration with data movement tools automates the availability of new data. In addition, the approach allows us to open up easy adhoc access to analyze and visualize data through SQL on Hadoop and popular BI tools. As we discuss our approach, we will also highlight how our approach minimizes data duplication, eliminates wasteful data retention, and solves for data provenance, lineage and integrity.
