----------------------------
Summary: Storage policy support in Erasure Coding
Key: HDFS-13920
URL: https://issues.apache.org/jira/browse/HDFS-13920
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: jagan
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.
