----------------------------------
Summary: 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
Reporter: Weiwei Yang
Assignee: Weiwei Yang
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.
