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?
