> Should be able to specify that a file be "fully" or "widely" replicated, rather than
an explicit replication count. This would be useful for job configuration and jar files, and
probably other files whose use is wide enough to necessitate reducing latency to access them.
> The current implementation will also complain if you specify replication that is wider
than the system's maximum replication value, and has no facility to enable "full" replication
should the number of datanodes exceed the current maximum settable value of 32k.
