Interface Summary
DNSToSwitchMapping An interface that should be implemented to allow pluggable DNS-name/IP-address to RackID resolvers.
NetUtils.HostResolver  
Node The interface defines a node in a network topology.
 

Class Summary
CachedDNSToSwitchMapping A cached implementation of DNSToSwitchMapping that takes an raw DNSToSwitchMapping and stores the resolved network location in a cache.
DNS A class that provides direct and reverse lookup functionalities, allowing the querying of specific network interfaces or nameservers.
NetUtils  
NetUtils.QualifiedHostResolver This an alternate resolver with important properties that the standard java resolver lacks: 1) The hostname is fully qualified.
NetUtils.StandardHostResolver Uses standard java host resolution
NetworkTopology The class represents a cluster of computer with a tree hierarchical network topology.
NodeBase A base class that implements interface Node
ScriptBasedMapping This class implements the DNSToSwitchMapping interface using a script configured via topology.script.file.name .
SocketInputStream This implements an input stream that can have a timeout while reading.
SocketOutputStream This implements an output stream that can have a timeout while writing.
SocksSocketFactory Specialized SocketFactory to create sockets with a SOCKS proxy
StandardSocketFactory Specialized SocketFactory to create sockets with a SOCKS proxy
