Question about BackupNode

Hi, guys, one question about Backup Node,

The code in Backup Node shows us the NamespaceID of BN must be same as NN,
but when I start BackupNode, I have to do Namenode.format - which means the
NamespaceID is a new one. Then I need to remove the ID and replace with the
one of NN. Does it necessary?

regards
