> DiskBalancer status command fails when passing DataNode ID instead of address
> -----------------------------------------------------------------------------

> Key: HDDS-15690
> URL: https://issues.apache.org/jira/browse/HDDS-15690
> Project: Apache Ozone
> Issue Type: Improvement
> Components: Ozone Datanode
> Affects Versions: 2.3.0
> Reporter: Arun Sarin
> Assignee: Gargi Jaiswal
> Priority: Minor
>
> ozone admin datanode diskbalancer status command fails when passing DataNode
> ID instead of address
> Minor (Usability / CLI Consistency)
> The {{ozone admin datanode diskbalancer status}} command currently only
> accepts a DataNode's network address/host string. If a user attempts to pass
> a valid {{datanodeUuid}} (DataNode ID), the command fails or throws an
> unsupported/invalid argument error.
> For better usability and alignment with other {{ozone admin}} commands (which
> typically support both UUIDs and addresses to identify cluster nodes), this
> command should be updated to resolve and accept the DataNode ID.
> {code:java}
> [root@Nodename ~]# ozone admin datanode list -id scm1
