> Key: HDFS-9940
> URL: https://issues.apache.org/jira/browse/HDFS-9940
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: balancer & mover
> Affects Versions: 2.6.0
> Reporter: John Zhuge
> Assignee: John Zhuge
> Priority: Minor
> Labels: supportability
>
> It is very confusing for both Balancer and Datanode to use the same property
> {{dfs.datanode.balance.max.concurrent.moves}}. It is especially so for the
> Balancer because the property has "datanode" in the name string. Many
> customers forget to set the property for the Balancer.
> Change the Balancer to use a new property
> {{dfs.balancer.max.concurrent.moves}}.
