[jira] [Created] (HDFS-6010) Make balancer able to balance data among specified servers

Yu Li created HDFS-6010:
---------------------------

             Summary: Make balancer able to balance data among specified servers
                 Key: HDFS-6010
                 URL: https://issues.apache.org/jira/browse/HDFS-6010
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: balancer
    Affects Versions: 2.3.0
            Reporter: Yu Li
            Priority: Minor


Currently, the balancer tool balances data among all datanodes. However, in some particular case, we would need to balance data only among specified nodes instead of the whole set.

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