Subject [jira] Created: (HADOOP-51) per-file replication counts
Date Tue, 21 Feb 2006 22:30:49 GMT
per-file replication counts

         Key: HADOOP-51
         URL: http://issues.apache.org/jira/browse/HADOOP-51
     Project: Hadoop
        Type: New Feature
  Components: dfs  
    Versions: 0.1    
    Reporter: Doug Cutting
     Fix For: 0.1

It should be possible to specify different replication counts for different files.  Perhaps
an option when creating a new file should be the desired replication count.  MapReduce should
take advantage of this feature so that job.xml and job.jar files, which are frequently accessed
by lots of machines, are more highly replicated than large data files.
