Subject [jira] [Created] (HADOOP-9485) inconsistent defaults for hadoop.rpc.socket.factory.class.default
Date Thu, 18 Apr 2013 22:57:15 GMT
Colin Patrick McCabe created HADOOP-9485:

             Summary: inconsistent defaults for hadoop.rpc.socket.factory.class.default
                 Key: HADOOP-9485
                 URL: https://issues.apache.org/jira/browse/HADOOP-9485
             Project: Hadoop Common
          Issue Type: Bug
          Components: net
    Affects Versions: 2.0.5-beta
            Reporter: Colin Patrick McCabe
            Assignee: Colin Patrick McCabe
            Priority: Minor

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.
