Kai Zheng commented on HDFS-7717: --------------------------------- As I re-purposed this and modified the description, this issue will focus on *stripping* erasure coding case. It stays in HDFS-8031 so will be done in phase 1. I created another one HDFS-8042 similar to this but will focus on *non-stripping* case, which targets for HDFS-8030 in phase 2. Am I clear ? > Erasure Coding: distribute replication to stripping erasure coding conversion > work to DataNode > ---------------------------------------------------------------------------------------------- > > Key: HDFS-7717 > URL: https://issues.apache.org/jira/browse/HDFS-7717 > Project: Hadoop HDFS > Issue Type: Sub-task > Reporter: Jing Zhao > Assignee: Kai Sasaki > > In *stripping* erasure coding case, we need some approach to distribute > conversion work between replication and 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
