tHDFSoutput failing

[Anonymous]

Hi,
Trying to write a file tMap --> tHDFSoutput 
receiving this:

could only be replicated to 0 nodes instead of minReplication (=1).  There are 3 datanode(s) running and 3 node(s) are excluded in this operation.

What am i doing wrong?

Hi
It seems the  dfs.datanode.address   port address is not open, you can find some explanation in this page.
