   When running a 2.1 manager, killing the tserver and then starting a 3.0 
tserver the "new" tserver fails to communicate with the manager.
   
   The manager log keeps repeating that it cannot get the status and cannot get 
it to halt (repeatedly) so it's obvious there is an issue with that tserver.
   
   The gc cannot scan the metadata  (Failed to locate tablet for table : +r row 
: ~del)
