HDFS scalability and availability is limited by the single namespace server design. Giraffa is an experimental file system, which uses HBase to maintain the file system namespace in a distributed way and serves data directly from HDFS DataNodes. Giraffa is intended to provide higher scalabilty, availability, and maintain very large namespaces. The presentation will explain the Giraffa architecture, the motivation, will address its main challenges, and give an update on the status of the project.
