I think we handled this over in HDFS-7165, which has been committed.

> Some users use replication level set to 1 for datasets which are unimportant and can be lost with no worry (eg the output of terasort tests). But other data on the cluster is important and should not be lost. It would be useful to separate the metric for missing blocks by the desired replication level of those blocks, so that one could ignore missing blocks at repl 1 while still alerting on missing blocks with higher desired replication.
