> "The reported blocks X needs additional Y blocks to reach the threshold 0.9990 of total
blocks Z. Safe mode will be turned off automatically.
> {code}
> We'd wonder what these blocks that still need block reports are, and what DNs they could
possibly be located, what happened to these DNs.
> This jira to to propose a new admin or debug tool to dump the block map info with the
blocks that have fewer than minRepl replicas.
