Subject [jira] [Created] (HDFS-7250) Store blocks in slabs rather than a Map inside BlocksMap
Date Tue, 14 Oct 2014 11:44:33 GMT
Amir Langer created HDFS-7250:
---------------------------------

             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.
