> hdfs scm -container create -p <pipelineID>
> Notes : This command connects to SCM and creates a container. Once the 
> container is created in the SCM, the corresponding container is created at 
> the appropriate datanode. Optional -p allows the user to control which 
> pipeline to use while creating this container, this is strictly for debugging 
> and testing.
> {noformat}
> it has 2 problems with this design, 1st it does support a container name but 
> it is quite useful for testing; 2nd it supports an optional option for 
> pipeline, that is not quite necessary right now given SCM handles the 
> creation of the pipelines, we might want to support this later. So proposed 
> to revise the CLI to
> {code}
> hdfs scm -container create -c <containerName>
> {code}
> the {{-c}} option is *required*. Backend it does following steps
> # Given the container name, ask SCM where the container should be replicated 
> to. This returns a pipeline.
> # Communicate with each datanode in the pipeline to create the container.
> this jira is to track the work to update both the design doc as well as the 
> implementation.
