Subject [jira] Created: (HADOOP-870) Store creation date for the files produced by Map Reduce
Date Tue, 09 Jan 2007 19:38:27 GMT
Store creation date for the files produced by Map Reduce
--------------------------------------------------------

                 Key: HADOOP-870
                 URL: https://issues.apache.org/jira/browse/HADOOP-870
             Project: Hadoop
          Issue Type: Improvement
          Components: mapred
            Reporter: arkady borkovsky


Being able to know when a file has been created it very useful.
While full support of files dates in DFS is a big task and does not seem to be going to happen
soon, it still would be good to intorduce a partial solution for Map Reduce.
Why don't we put the date into the file names?
Instead of 
  part-00000
the name would be
  part-00000-07-01-08-11:35:20
or something like this.

This may make life so much easier....
