------------------------------------
Hi [~anu], please let me know how to update the design doc in HDFS-11470. Maybe
we could add this doc to an online editor? Thanks.
> Ozone: Revise create container CLI specification and implementation

> Key: HDFS-11725
> URL: https://issues.apache.org/jira/browse/HDFS-11725
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: ozone

> Per [design
> doc|https://issues.apache.org/jira/secure/attachment/12861478/storage-container-manager-cli-v002.pdf]
> in HDFS-11470
> {noformat}
> 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.
