A simple replication-based
mechanism has been used to achieve high data reliability of Hadoop Distributed
File System (HDFS). However, replication based mechanisms have high degree of
disk storage requirement since it makes copies of full block without
consideration of storage size.
Using erasure-coding we can reduce the storage size of HDFS.
Erasure codes store data
objects as equations thus reducing much of the storage cost.
