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

             Summary: BlockPlacementPolicy shoud choose storage but not datanode for deletion
                 Key: HDFS-6700
                 URL: https://issues.apache.org/jira/browse/HDFS-6700
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Tsz Wo Nicholas Sze
            Assignee: Tsz Wo Nicholas Sze
            Priority: Minor
         Attachments: h6700_20140717.patch

HDFS-2832 changed datanode storage model from a single storage, which may correspond to multiple
physical storage medias, to a collection of storages with each storage corresponding to a
physical storage media.

BlockPlacementPolicy.chooseReplicaToDelete still chooses replica in term of 
DatanodeDescriptor but not DatanodeStorageInfo.
