-RE: For a new installation: use the BackupNode or the CheckPointNode?

So... the answer is... SecondaryNameNode is what I should be installing
here. And the SecondaryNameNode is essentially just an earlier version of
the checkpoint node, in terms of functionality. If I understood everything
correctly. Can you confirm?

Neither CheckpointNode nor BackupNode exists in version 1.x. This was a
documentation oversight that should be cleared in the docs now (or by next
release I think).
And on 2.x, neither has been tested for stability and the SecondaryNameNode
continues to exist and is fully supported (not deprecated).
