org.apache.hadoop.yarn.api.protocolrecords.GetClusterNodesResponse

The response sent by the ResourceManager to a client requesting a {@link NodeReport} for all nodes.
The NodeReport contains per-node information such as available resources, number of containers, tracking url, rack name, health status etc. @see NodeReport @see ClientRMProtocol#getClusterNodes(GetClusterNodesRequest)
