Description

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
