             Summary: Erasure Coding: distribute replication to non-stripping erasure coding
conversion work to DataNode
                 Key: HDFS-8042
                 URL: https://issues.apache.org/jira/browse/HDFS-8042
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Kai Zheng
            Assignee: Vinayakumar B


In *non-stripping* erasure coding case, we need some approach to distribute conversion work
between replication and non-stripping erasure coding to DataNode. It can be NameNode, or a
tool utilizing MR just like the current distcp, or another one like the balancer/mover.
