Description

+        RegionPlan newPlan = plan;
+        if (!regionAlreadyInTransitionException) {
+          // Force a new plan and reassign. Will return null if no servers.
+          newPlan = getRegionPlan(state, plan.getDestination(), true);
+        }
+        if (newPlan == null) {
           this.timeoutMonitor.setAllRegionServersOffline(true);
           LOG.warn("Unable to find a viable location to assign region " +
             state.getRegion().getRegionNameAsString());

Here, when newPlan is null, plan.getDestination() could be up actually.
