[jira] [Created] (HDFS-4353) Encapsulate connections to peers in Peer and PeerServer classes

Colin Patrick McCabe created HDFS-4353:
------------------------------------------

             Summary: Encapsulate connections to peers in Peer and PeerServer classes
                 Key: HDFS-4353
                 URL: https://issues.apache.org/jira/browse/HDFS-4353
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: datanode, hdfs-client
    Affects Versions: 2.0.3-alpha
            Reporter: Colin Patrick McCabe
            Assignee: Colin Patrick McCabe
         Attachments: 02-cumulative.patch

Encapsulate connections to peers into the {{Peer}} and {{PeerServer}} classes.  Since many Java classes may be involved with these connections, it makes sense to create a container for them.  For example, a connection to a peer may have an input stream, output stream, readablebytechannel, encrypted output stream, and encrypted input stream associated with it.

This makes us less dependent on the {{NetUtils}} methods which use {{instanceof}} to manipulate socket and stream states based on the runtime type.  it also paves the way to introduce UNIX domain sockets which don't inherit from {{java.net.Socket}}.
