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

             Summary: Allows to run multiple balancer simultaneously
                 Key: HDFS-6300
                 URL: https://issues.apache.org/jira/browse/HDFS-6300
             Project: Hadoop HDFS

          Components: balancer

            Assignee: Rakesh R
