    Description

      Currently we use storage policy in hadoop where we use an archival machine with higher storage to store the 2nd & 3rd copy or just the 3rd copy as part of optimization.

      Post Erasure coding, hope storage policy will be supported and there will be options to place just the parity blocks in an archival server. This way the main read/writes wont be hitting the archival servers.
