Once NNA is up and running, have you tried running hitting the /fetchNamespace endpoint? Your issue is that NNA has no FSImage to boot from.

Are you running with nna.bootstrap.auto.fetch.namespace=true in the application.properties file?

If it is set to false, switch it to true and restart NNA. It should automatically format and load the namespace after fetching it from the current active NameNode.
