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

             Summary: Store blocks in slabs rather than a Map inside BlocksMap
                 Key: HDFS-7250
                 URL: https://issues.apache.org/jira/browse/HDFS-7250
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Amir Langer


Key to every block is the replication factor + slab key (address).
When setting a different replication factor for a block we need to move its 
data from one slab to another.
