>
> Once ROOT and META are assigned, ServerShutdownHandler is enabled. So that we
> can handle meta/root region server failure before joinCluster is completed.
> However, we can hold ServerShutdownHandler a little bit more for the user
> region assignments, i.e. doesn't assign user regions before joinCluster is
> returned. If so, we can avoid some region assignments racing: same regions
> are trying to be assigned in both joinCluster and ServerShutdownHandler.
