---------------------------------
Summary: ozone admin datanode 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
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.
