             Summary: Ozone: misc improvements for SCM CLI
                 Key: HDFS-11668
                 URL: https://issues.apache.org/jira/browse/HDFS-11668
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Weiwei Yang
            Assignee: Weiwei Yang


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 commands
# Better error messages when missing some key ozone configurations, e.g {{ozone.scm.names}}, {{ozone.scm.datanode.id}} ... etc
# Property {{ozone.enabled}} is not honored, don't know why yet
# 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.
