Weiwei Yang commented on HDFS-11679:
------------------------------------
Hi [~yuanbo]
Thanks for the updates. Mostly seem good to me, I think we just need to address
2 issues please
1. {{-start}} should be optional
{code}
-start <arg> Specify start container name, required
{code}
We need to make {{-start}} argument optional. If it is not given, then list the
first container. This is how user to use this CLI. User doesn't know a
container name for the first call at most of the time.
2. When output json, can we use pretty printer. In pipeline, can we init
WRITTER like following?
{code}
ObjectWriter WRITTER = MAPPER.writerWithDefaultPrettyPrinter();
{code}
thanks

> Implement the command to list containers
> {code}
> hdfs scm -container list -start <container name> [-count <100> | -end
> <name>]{code}
> Lists all containers known to SCM. The option -start allows the listing to
> start from a specified container and -count controls the number of entries
> returned but it is mutually exclusive with the -end option which returns keys
> from the -start to -end range.
