The clustername
method nn_hostname : string
The hostname of this node. Must be resolvable to a reasonable
IP address so that other nodes can reach this node.
method nn_nodes : string list
The name nodes in "host:port" syntax
method nn_node_timeout : float
The timeout for connects and RPC calls to name nodes
method nn_node_alive_min : int
How many name nodes need to be alive to continue with operations
