Sreeja updated HDDS-13486:
--------------------------
Description:
Currently, the ozone admin datanode list command allows users to combine node
selection options (e.g., --node-id, --ip, --hostname) with usage sorting
options (e.g., --most-used, --least-used).
This combination leads to confusing command behaviour. For instance,
{code:java}
ozone admin datanode list --most-used=true --ip=<IP Address>{code}
will attempt to get all the nodes in increasing order of usage but then filter
to a single node with the given IP. This provides a misleading output to the
user. To improve command clarity and user experience, we need to make node
selection options and usage sorting options mutually exclusive. This means a
user will only be able to specify options for either selecting specific nodes
or sorting the entire list by usage, but not both simultaneously. This ensures
the command's intent is clear and its output is intuitive.
