> Executor's heartbeat will send synchronously to BlockManagerMaster to let it know that the block manager is still alive. In a heavy cluster, it will timeout and cause block manager re-register unexpected.
> This improvement will separate a heartbeat endpoint from the driver endpoint. In our production environment, this is really helpful to prevent executors from unstable up and down.
