Subject: Questions about BN and CN

Hi all,

 I got the Backup node(BN) that includes all the checkpoint
responsibilities,
 and it maintains an up-to-date namespace state, which is always in
sync with the active NN.

 Q1. In which situation do we need a CN?

 Q2. If the NameNode machine fails, which different manual
intervention between BN and CN?

Thanks.

Shen
