hey, Can we access NameNode's hdfs on our slave machines ??
I am just running command "hadoop dfs -ls" on my slave machine ( running tasktracker and Datanode), and its giving me the following output : hadoop@ub12:~$ hadoop dfs -ls 11/05/05 18:31:54 INFO ipc.Client: Retrying connect to server: ub13/ 162.192.100.53:54310.
