---------------------------

             Summary: Make it able to specify balancer bandwidth for specified 
nodes
                 Key: HDFS-6011
                 URL: https://issues.apache.org/jira/browse/HDFS-6011
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: tools
    Affects Versions: 2.3.0
            Reporter: Yu Li
            Assignee: Yu Li
            Priority: Minor


Currently, we can only specify balancer bandwidth for all datanodes. However, 
in some particular case, we would need to balance data only among specified 
nodes thus don't need to throttle bandwidth for all nodes

In this JIRA, a new "-servers" option would be introduced to implement this.
