Christos Bisias updated HDDS-7329:

Summary: Extend ozone admin datanode usageinfo and list info to accept
hostname parameter (was: Extend ozone admin datanode usageinfo and list info
to accept --hostname parameter)

> Key: HDDS-7329
> URL: https://issues.apache.org/jira/browse/HDDS-7329
> Project: Apache Ozone
> Issue Type: Bug
> Reporter: Christos Bisias
> Assignee: Christos Bisias
> Priority: Major
>
> Ozone admin datanode subcommands should be more consistent. Some of them
> accept hostname as a parameter, others don't. Extend usageinfo and list info
> to accept hostname in addition to uuid and ip address.
> There is an hdfs flag *dfs.datanode.use.datanode.hostname* checked by the
> SCMNodeManager during start up and if it's true then we can get the datanode
> info by providing the hostname with the --ip pamameter, while ip will not be
> available anymore.
> If we add the --hostname parameter and keep the flag, then it's confusing for
> the user. We should deprecate the flag and in every case that it is checked,
> keep the default usage, which is having value false. This way, --ip will
> always require the ip and if the user needs to get the info with the
> hostname, he can use the --hostname parameter.
