Ethan Rose commented on HDDS-9700:
----------------------------------
Yes that is valid json, but I still think it would be better to have errors go
to stderr and normal output go to stdout. This is somewhat standard among CLI
tools like {{time}} for example, which prints the time results to stderr to
avoid the pipe. See HDDS-8858 for reference as well.
> Allow ozone admin container info to list multiple containers

> Key: HDDS-9700
> URL: https://issues.apache.org/jira/browse/HDDS-9700
> Project: Apache Ozone
> Issue Type: Improvement
> Components: SCM Client
> Reporter: Stephen O'Donnell
> Assignee: Stephen O'Donnell
> Priority: Major
>
> Currently the command:
> {code}
> ozone admin container info 1234
> {code}
> Only accepts a single container ID. If you need to list the details from many
> containers, then the JVM startup overhead makes the command very slow.
> Therefore it would be useful to allow a list of IDs to be specified so a
> single JVM instance can retrieve all the details in a single call.
> The logic should handle invalid IDs and "unknown to SCM containers" by
> printing an error and continuing to the next ID rather than failing.
> For the JSON output, it probably makes sense to output a JSON array rather
> than a series of individual JSON blob, so the entire output can be pass to a
> JSON tool without modification.
