> Currently on master restart if it tries to do processRIT, any region if found on dead server tries to avoid the nwe assignment so that timeout monitor can take care.
> This case is more prominent if the node is found in RS_ZK_REGION_OPENING state. I think we can handle this by triggering a new assignment with a new plan.
