> In {{core-default.xml}}, {{hadoop.rpc.socket.factory.class.default}} defaults
> to {{org.apache.hadoop.net.StandardSocketFactory}}. However, in
> {{CommonConfigurationKeysPublic.java}}, there is no default for this key.
> This is inconsistent (defaults in the code versus defaults in the XML files
> should match.) It also leads to problems with {{RemoteBlockReader2}}, since
> the default {{SocketFactory}} creates a {{Socket}} without an associated
> channel. {{RemoteBlockReader2}} cannot use such a {{Socket}}.
> This bug only really becomes apparent when you create a {{Configuration}}
> using the {{Configuration(loadDefaults=true)}} constructor. Thanks to AB
> Srinivasan for his help in discovering this bug.
