Andrew Wang resolved HDFS-600.

    Resolution: Won't Fix

This one goes back to the HDFS-RAID days, which has been removed. EC has also been implemented
natively at HDFS-7285. Closing as won't fix.

> HDFS-503 introduces erasure coding for HDFS files. It currently uses "xor" algoritm as
the Erasure coding algorithm. It would be nice if that Erasure Coding framework supports a
pluggable API to allow plugging in other Erasure Coding policies.  A few of these policies
are mentioned by Hong at https://issues.apache.org/jira/browse/HDFS-503?focusedCommentId=12735011&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#action_12735011
