---------------------------------
Summary: Create PicoCLI mixin to standardize datanode selection
options
Key: HDDS-13098
URL: https://issues.apache.org/jira/browse/HDDS-13098
Project: Apache Ozone
Issue Type: Sub-task
Reporter: Ethan Rose
The options to filter datanodes in commands like {{ozone admin datanode
usageinfo}} and {{ozone admin datanode decommission}} should be consistent.
Right now there are divergences among the various commands, including mixed use
of {{--id}} or {{--uuid}} to filter by datanode ID, and commands that only
support selection based on host name.
Create a PicoCLI mixin that provides a standardized set of node selection
options that can be re-used for all relevant commands:
* {{--node-id}} for datanode UUID
** This is consistent with ID based selection for OM and SCM commands like
{{{}ozone admin om decommission{}}}.
** {{--id}} is confusing with the SCM service ID option that some commands
also take, which has the short form {{{}-id{}}}.
** {{--uuid}} couples the flag to the ID generation algorithm unnecessarily.
* {{--hostname}} for datanode host
* {{--ip}} for datanode IP address
Commands using other selection flags will need to have those flags hidden and
deprecated from the CLI while left in place in the code to maintain
compatibility.
