Doug,
Could you please take a look at three JIRA issues that sitting there for
quite a while now:
http://issues.apache.org/jira/browse/HADOOP-42
http://issues.apache.org/jira/browse/HADOOP-40
http://issues.apache.org/jira/browse/HADOOP-33
The first two are actually bugs that produce incorrect results as I
write it.
The last one is an improvement, which would not heart any existing
functionality.
It would be good to resolve them one way or another.
Thanks,
--Konst

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
Assignee: Konstantin Shvachko
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.
