[jira] [Created] (HDFS-9940) New property dfs.balancer.max.concurrent.moves for Balancer

John Zhuge created HDFS-9940:
--------------------------------

             Summary: New property dfs.balancer.max.concurrent.moves for Balancer
                 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
             Fix For: 2.8.0


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}}.
