Examples of DatanodeID

org.apache.hadoop.dfs.DatanodeID
DatanodeID is composed of the data node name (hostname:portNumber) and the data storage ID, which it currently represents. @author Konstantin Shvachko
org.apache.hadoop.hdfs.protocol.DatanodeID
This class represents the primary identifier for a Datanode. Datanodes are identified by how they can be contacted (hostname and ports) and their storage ID, a unique number that associates the Datanodes blocks with a particular Datanode. {@link DatanodeInfo#getName()} should be used to get the networklocation (for topology) of a datanode, instead of using {@link DatanodeID#getXferAddr()} here. Helpers are defined belowfor each context in which a DatanodeID is used.
