Uses of Peer in org.apache.hadoop.hdfs.net

Classes in org.apache.hadoop.hdfs.net that implement Peer

Modifier and Type	Class	Description
class	BasicInetPeer	Represents a peer that we communicate with by using a basic Socket that has no associated Channel.
class	DomainPeer	Represents a peer that we communicate with by using blocking I/O on a UNIX domain socket.
class	EncryptedPeer	Represents a peer that we communicate with by using an encrypted communications medium.
class	NioInetPeer	Represents a peer that we communicate with by using non-blocking I/O on a Socket.
