> We propose to implement Erasure Coding in Apache Ozone to provide efficient storage. With EC in place, Ozone can provide same or better tolerance by giving 50% or more  storage space savings. 
> In HDFS project, we already have native codecs(ISAL) and Java codecs implemented, we can leverage the same or similar codec design.
> However, the critical part of EC data layout design is in-progress, we will post the design doc soon.
