hadoop-a small doubt

[deepya]

Hi,
   I am SreeDeepya doing MTech in IIIT.I am working on a project named cost effective and scalable storage server.I configured a small hadoop cluster with only two nodes one namenode and one datanode.I am new to hadoop.
I have a small doubt.

Can a system not in the hadoop cluster access the namenode or the datanode????If yes,then can you please tell me the necessary configurations that has to be done.

Thanks in advance.

Hey ,
You can do that.That system should have same usrname like those of cluster and ofcourse it  should be able to ssh name node.Also it should have hadoop and its hadoop-site.xml should be similar .Then u can access namenode,hdfs etc.

if you are willing to see the web interface that can be done easily using any system.

What is the exact purpose that you want a system not in hadoop cluster to access the namenode or datanode? If it is simply to write data to HDFS from local system and then to copy back data from HDFS to local system simply use hadoop file system's shell commands.

Hope this helps!
