Lou DeGenaro commented on UIMA-5060:
------------------------------------

Previously OR supported --cold and --warm starts, where the former caused all 
active work to be moved to the Completed state (no recovery) and the latter 
caused partial recovery (active Jobs forced to Completed, while active 
Reservations recovered).  We abandon introducing a third --hot option that 
would implement a full recovery and instead re-purpose --warm to do so.  
Partial recovery is deemed unnecessary and somewhat arbitrary.
