      Description

      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..
