Abstract
The Hadoop Distributed File System is not just a filesystem, but also a file access protocol. This talk describes how OneFS has implemented HDFS as a protocol on top of OneFS. It describes how the OneFS implementation maps HDFS features into a POSIX-like distributed filesystem. There is also analysis of benefits and drawbacks to the OneFS HDFS implementation compared to the Apache HDFS implementation.
Learning Objectives
HDFS NameNode and DataNode protocols
OneFS implementation of the HDFS protocols
Differences between Apache HDFS implementation and the OneFS protocol-only implementation
