ZombieCluster

public ZombieCluster(LoggedNetworkTopology topology,
             MachineNode defaultNode)

Construct a homogeneous cluster. We assume that the leaves on the topology are MachineNodes, and the parents of MachineNodes are RackNodes. We also expect all leaf nodes are on the same level.

参数:

topology - The network topology.

defaultNode - The default node setting.

ZombieCluster

public ZombieCluster(Path path,
             MachineNode defaultNode,
             Configuration conf)
              throws IOException

Construct a homogeneous cluster. We assume that the leaves on the topology are MachineNodes, and the parents of MachineNodes are RackNodes. We also expect all leaf nodes are on the same level.

参数:

path - Path to the JSON-encoded topology file.

conf -

defaultNode - The default node setting.

抛出:

IOException

ZombieCluster

public ZombieCluster(InputStream input,
             MachineNode defaultNode)
              throws IOException

Construct a homogeneous cluster. We assume that the leaves on the topology are MachineNodes, and the parents of MachineNodes are RackNodes. We also expect all leaf nodes are on the same level.

参数:

input - The input stream for the JSON-encoded topology file.

defaultNode - The default node setting.

抛出:

IOException

getClusterTopology

public Node getClusterTopology()

从接口复制的说明: ClusterStory

Get the cluster topology tree.

返回:

The root node of the cluster topology tree.
