Socket Factories in hadoop

[Ahmad Shahzad <as...@gmail.com>]

Hi ALL,
           Where can i find the socket factories that are used by hadoop to
create its sockets. By this i mean to say that map-reduce framework of
hadoop along with HDFS uses sockets to communicate with each other. So, i am
looking for socket factories that hadoop framework uses to carry out its
work. I looked into the hadoop directory and could find SocksSocketFactory
and StandardSocketFactory java classes in core/org/apache/hadoop/net
directory. Are these the only socket factories used by hadoop or is there
any more??

One more thing, can i create my own socket factory and use that to create
sockets that can be used by hadoop??

Hello,
You can define your own SocketFactory. Have a look at the method:
public static SocketFactory getSocketFactory(Configuration conf,
      Class<?> clazz){...} in the class org.apache.hadoop.net.NetUtils.java

Cheers,
Himanshu
