Harsh J resolved HDFS-251.

    Resolution: Duplicate

Duplicate of https://issues.apache.org/jira/browse/HDFS-782 (closing this one, since the other
has more discussions in it regarding dynamic replication)

> Automatically increase replication of often used files/blocks

>                 Key: HDFS-251
>                 URL: https://issues.apache.org/jira/browse/HDFS-251

> 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?
