> Reproducing steps
> # Start datanode
> # Wait and see datanode state, it has connection issues, this is expected
> # Start SCM, expecting datanode could connect to the scm and the state
> machine could transit to RUNNING. However in actual, its state transits to
> SHUTDOWN, datanode enters chill mode.
