Thanks, data node may not be known. Is it possible to direct url to namenode and namenode handling streaming by fetching data from various data nodes?
If you access the servlet on the NameNode, it will automatically redirect you to a data node that has some of the data on it. You certainly should not pick a random data node yourself.
Also note that in yahoo 0.20.104 or 0.22, you'll need a Kerberos ticket or delegation token to use the servlet.
