>
> New pattern where we throw exception on procedure construction if cluster is
> going down, hosting master is stopping, table is offline, or table is
> read-only. Fail fast rather than later internal to Procedure so can flag
> caller there is a problem.
> Changed Move/Split/Merge Procedures.
> No point queuing a move region for a table that is offline and which may
> never be re-enabled.
