Re: Is it OK to run with no secondary namenode?

[Mayuran Yogarajah]

Hey Todd,

Note that you do not need to run the 2NN on a separate machine *if* you have
enough RAM for two entire copies of your filesystem namespace. For small
clusters you should be fine to run the two daemons on one machine.
  
Just wanted to confirm.. to set up the secondary NN I just need to add 
the hostname
into the slaves file, correct?

thanks again.
