----------------------------------------
This would be better as a CLI command and/or available via the metrics system.

> Sometimes admins want to know the list of "very-under-replicated blocks"
> before major actions such as decommission; as these blocks are more likely to
> turn into missing blocks. "very-under-replicated blocks" are those blocks
> with live replica count of 1 and replicator factor of >= 3.
