JiangHua Zhu updated HDDS-11083:
--------------------------------
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.
