If I understand correctly the TM can request the heartbeat to itself and
the JM also can send the heartbeat to itself?
If it is true, the **requestHeartbeat** will never be called from current
logic in TM side. Or I can just remove the **UnsupportedOperationException** to
not limitation and leave this method empty currently?
