Abstract
Hadoop 2.0 offers significant HDFS improvements: new append-pipeline, federation, wire compatibility, NameNode HA, performance improvements, etc. We describe these features and their benefits. We also discuss development that is underway for the next HDFS release. This includes much needed data management features such as Snapshots and Disaster Recovery. We add support for different classes of storage devices such as SSDs and open interfaces such as NFS; together these extend HDFS as a more general storage system. As with every release we will continue improvements to performance, diagnosability and manageability of HDFS.
