Description

In DN, it is a regular operation to send heartbeats to SCM/Recon.
When DatanodeStates=RUNNING, some objects are repeatedly created every time a heartbeat occurs: RunningDatanodeState, VersionEndpointTask, RegisterEndpointTask, HeartbeatEndpointTask. If these objects are created every time, additional resources will be consumed. The best way is to reuse them once they are created successfully.
