Thanks [~cheersyang] for working on this. The patch looks good to me. I only have one minor

Can we change the log level from info to debug in StateContext.java Line 194?

>                 Key: HDFS-11668
>                 URL: https://issues.apache.org/jira/browse/HDFS-11668
>             Project: Hadoop HDFS
>          Issue Type: Sub-task

> Once HDFS-11649 is done, there are some improvements need to be done in order to make
SCM CLI better to use in a pseudo cluster, this includes
> # HDFS-11649 adds java classes for CLIs, we will need to add shell code to expose these
> # Better error messages when missing some key ozone configurations, e.g {{ozone.scm.names}},
{{ozone.scm.datanode.id}} ... etc
> # Better logging. Currently {{DatanodeStateMachine}} prints very limited logs, adds some
more logs to indicate state transition is necessary.
> The ultimate goal of this ticket is to ensure SCM CLI can work nicely on a pseudo cluster.
