------------------------------------------------------------
Before I provide a patch for this JIRA, I's propose to get rid of the option
{{-end}}
There are two cases while users use such kind of command {{hdfs scm -container
list -start <name> -end <name>}}:
* The end container name should be in the same datanode with start container
name, otherwise users cannot get the list in current architecture.
* The users needs to know that the end container is actually behind of the
start container, otherwise it returns nothing. It's hard for users to notice
the order ozone stores container names.
