DescriptionHCatalog is a metadata and table management system for Hadoop. It allows users to share data and metadata across Hive, Pig, and MapReduce. It also allows users to write their applications without being concerned how or where the data is stored, and insulates users from schema and storage format changes. In this talk, Hortonworks founder Alan Gates will introduce HCatalog, discuss its current features, and give an overview of the short term roadmap for HCatalog. Alan is an original member of the engineering team that took Pig from a Yahoo! Labs research project to a successful Apache open source project. He also also designed HCatalog and guided its adoption as an Apache Incubator project.
