Subject [jira] [Created] (HDFS-6828) Separate block replica dispatching from Balancer
Date Wed, 06 Aug 2014 06:11:12 GMT
Tsz Wo Nicholas Sze created HDFS-6828:
-----------------------------------------

             Summary: Separate block replica dispatching from Balancer
                 Key: HDFS-6828
                 URL: https://issues.apache.org/jira/browse/HDFS-6828
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: balancer
            Reporter: Tsz Wo Nicholas Sze
            Assignee: Tsz Wo Nicholas Sze


The Balancer class implements two major features, (1) balancing logic for selecting replicas
in order to balance the cluster and (2) block replica dispatching for moving the block replica
around.  This JIRA is to separate (2) from Balancer so that the code could be reused by other
code such as the new data migration tool proposed in HDFS-6801.
