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.
