AIRCRAFT WAS GROUNDED: DURING INITIAL CLIMB YELLOW HYDRAULIC RESERVOIR OVER HEAT ECAM MESSAGE OCCURRED. CREW ACCOMPLISHED ECAM NON-NORMAL PROCEDURE BUT THE OVERHEAT CONDITION PERSISTED SO THE CREW SHUT DOWN THE YELLOW HYDRAULIC PUMPS AND THE OVER HEAT CONDITION  WENT AWAY. AN EMERGENCY WAS DECLARED AND  THE AIRCRAFT LANDED SAFELY AT THE DESTINATION (DFW) WITHOUT FURTHER INCIDENT. MAINTENANCE ACCOMPLISHED TEST OF YELLOW HYDRAULIC SYSTEM PER AMM 29-13-0-710-002-A WITH NO FAULTS BEING NOTED.
