Re: updating datanode config files on namenode recovery
Hi Sumadhur,

The easier approach is to make the hostname of the new NN same as the old one, else you'll have to update the new one on config files across cluster.

Subject: updating datanode config files on namenode recovery

When a name node goes down and I bring up another machine as the new name node using the back up on a shared folder, do I have to update config files in each data node to point to the new name node and job tracker manually?
 
Or is there some other way of doing it automatically?
 
Thanks,
Sumadhur
