Node join not committed

Hi Daniel,

It's perfectly safe to issue the cluster plan/commit steps.  Joining the
node gives it information about where data is located in the rest of the
cluster and it will happily coordinate gets, but the new node will always
forward put requests and will not store any data until you go through the
plan/commit cycle.

If you cancel the node will remove itself from the cluster membership
metadata and exit.

Jon
