Hadoop Distributed Filesystem – HDFS
is the world’s most reliable storage system. HDFS is a Filesystem of
Hadoop designed for storing very large files running on a cluster of
commodity hardware. HDFS is designed on principle of storage of less
number of large files rather than the huge number of small files. It
provides fault tolerant storage layer for Hadoop and its other
components. Replication of data helps us to attain this feature. It
stores data reliably even in the case of hardware failure. It provides
high throughput access to application data by providing the data access
in parallel.
