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-11649adds java classes for CLIs, we will need to add shell code to expose these commands
- 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.
