HDFS: The Hadoop Distributed File System (HDFS)
is a distributed file system
designed to run on commodity hardware. It has many similarities
with existing distributed file systems. However, the differences from
other distributed file systems are significant. HDFS is highly
fault-tolerant and is designed to be deployed on low-cost hardware.
HDFS provides high throughput access to application data and is
suitable for applications that have large data sets.
