Functions of Secondary Name node

There is a quiz Q:
Can Secondary NameNode takeover as NameNode if NameNode fails?

I think we did not cover the explanation for this quite well in the class? Shobhan, would you be able to explain this in the class? Thanks

hi Karuna,

SNN cannot takeover as NameNode if NN fails. SNN is only a backup node and its job is to take backup of fsimage and editlog files.
