----------------------------------
[~mladjangadzic] I was asking about a different scenario. I'm wondering if we
can see all CLOSED containers with replicas in states like UNHEALTHY CLOSED
CLOSED. This would be useful to check if things are getting repaired in the
cluster. An easy way to simulate this would be to move the container state in
one of the .container files in the datanodes to UNHEALTHY and restarting it. A
more realistic setup would involve editing a .block file in the container to
violate the checksum and enabling the WIP container scanner from HDDS-7364.

> Currently UNHEALTHY is a state that a container replica can be in
> (ContainerReplicaProto#State), but not a state that the container can be in
> overall (LifeCycleState). This means {{ozone admin container list}} has no
> info about unhealthy containers, because it currently does not print replica
> information. [Recon's
> API|https://ozone.apache.org/docs/current/interface/reconapi.html] and UI
> does not expose replica information either. The only way to determine
> unhealthy containers is to run {{ozone admin container info <ID>}} for a
> container that is already suspected to have unhealthy replicas. This jira
> aims to provide a way to identify and filter container replica states,
> through either Recon's UI, Recon's REST API, or client CLI.
