Expert Contributor

Hello team.

I've just applied the recommended smartsense setting to make my dfs.namenode.checkpoint.period more efficent and I want to take a measure on how fast is now my namenode recovering from an restart than it was before.

Where can I get an old lecture from the nn last restart and how much time did it take?

Regards!

If you are using Ambari - you can find that from task logs in the UI.
