> # "Effective replication multiplier" is confusing and prints a strange number
> # Datanodes available: 3 - should count only live nodes.
> # A dead node "State" should not be "In Service".
> # "% used:" should not print "NaN%"
> # We should synchronize dfsadmin reporting with the what we report via the web UI.
> Field names and numbers should be the same.
