This material provides an overview of the HDFS (Hadoop Distributed File
System) architecture and is intended for contributors. The goal of this
document is to provide a guide to the overall structure of the HDFS code so
that contributors can more effectively understand how changes that they are
considering can be made, and the consequences of those changes. The assumption
is that the reader has a basic understanding of HDFS, its purpose, and how it
fits into the Hadoop project suite.
The Hadoop project URL is http://hadoop.apache.org/hdfs/
. An overview of HDFS can be found at
