> The current message shown is something such as below:
> bq. Failed to add a datanode. User may turn off this feature by setting X.policy in configuration,
where the current policy is Y. (Nodes: current=\[foo\], original=\[bar\])
> This reads off like failing is a feature (but the intention and the reason we hit this
isn't indicated strongly), and can be bettered.
