Date Wed, 26 Jan 2011 11:24:10 GMT

I'm confused about the architecture of HDFS
I have a client java write a files on a master node. It´s work perfect!..
well i see a HDFS architecture
some client access a data note..

i try use my java client write direct on slave node. I change IP on client
                Configuration conf = new Configuration();
conf.set("fs.default.name","hdfs://"); //slave ip

I got this error. .

In architecture picture show me that all datanode can conectable. That´s
correct ?

I can only conect to write on HDFS on master node ??
