Subject: Read/write into HDFS

Dear all,
I have set up a Hadoop cluster of 10 nodes.
I want to know that how we can read/write file from HDFS (simple).
Yes I know there are commands, i read the whole HDFS commands.
bin/hadoop -copyFromLocal tells that the file should be in localfilesystem.

But I want to know that how we can read these files from  the cluster.
What are the different ways to read files from HDFS.
Can a extra node ( other than the cluster nodes )  read file from the 
If yes , how?

Thanks in Advance
