> We see a lot of escalations because someone has written teragen output with a
> replication factor of 1, a DN goes down, and a bunch of missing blocks show
> up. These are normally false positives, since teragen output is disposable,
> and generally speaking, users should understand this is true for all repl=1
> files.
> It'd be nice to be able to separate out these repl=1 missing blocks from
> missing blocks with higher replication factors..
