Doug Cutting resolved HADOOP-51:
--------------------------------
Resolution: Fixed
I just committed this. I fixed the comment on dfs.replication.min. I also
added a message to CHANGES.txt.
Thanks, Konstantin!
Bryan: I think the issues you raise bear further discussion that I do not wish
to stifle. For example, we may someday want to be able to specify more than
2^16 replications, and we may wish to handle replication requests outside of
the configured limits differently. But, for now, I think the patch fixes this
bug and that those issues can be addressed though subsequent bugs as we gain
experience. So please file new bugs for any related issues that are important
to you.

> 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.
