> 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.
