[jira] Created: (HADOOP-504) Automatically increase replication of often used files/blocks

Automatically increase replication of often used files/blocks
-------------------------------------------------------------

                 Key: HADOOP-504
                 URL: http://issues.apache.org/jira/browse/HADOOP-504
             Project: Hadoop
          Issue Type: New Feature
          Components: dfs
    Affects Versions: 0.5.0
            Reporter: Johan Oskarson


It would be interesting to see if a patch that makes the namenode save the number of times a certain
file (or block if possible) is used. And then increase the replication of these files to increase performance.

Any ideas on how to implement?
