The current major release, Apache Hadoop 2.0 offers several significant HDFS improvements including new append-pipeline, federation, wire compatibility, NameNode HA, and performance improvements. In this session, we describe how to take advantages of these new features and their benefits. We cover some architectural improvements in detail such as HA and Federation. The second half of the talk describes the current features that are under development 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. Hadoop has recently been extended to run first-class on Windows which expands its enterprise reach and allows integration with the rich tool-set available on Windows. As with every release we will continue improvements to performance, diagnosability and manageability of HDFS. To conclude we discuss the reliability, the state of HDFS adoption and some of the misconceptions and myths about HDFS.
