Transparent archival and restore of files from HDFS
---------------------------------------------------

                 Key: HADOOP-4058
                 URL: https://issues.apache.org/jira/browse/HADOOP-4058
             Project: Hadoop Core
          Issue Type: New Feature
          Components: dfs
            Reporter: dhruba borthakur
            Assignee: dhruba borthakur


There should be a facility to migrate old files away from a production cluster. Access to
those files from applications should continue to work transparently, without changing application
code, but maybe with reduced performance. The policy engine  that does this could be layered
on HDFS rather than being built into HDFS itself.
