      Description

      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.
