---------------------------------
Hi, [~jingzhao]. I'm interested in this jira. I think it's related to HDFS-7613
which I'm working on. Can you assign this jira to me? Or maybe you already have
some progress?
> Erasure Coding: update the Balancer/Mover data migration logic
> --------------------------------------------------------------
>
> Key: HDFS-7621
> URL: https://issues.apache.org/jira/browse/HDFS-7621
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Reporter: Jing Zhao
> Assignee: Jing Zhao
>
> Currently the Balancer/Mover only considers the distribution of replicas of
> the same block during data migration: the migration cannot decrease the
> number of racks. With EC the Balancer and Mover should also take into account
> the distribution of blocks belonging to the same block group.
