[the-bling]

Running the command keystone-manage mapping_purge, no output is given but I get these messages in keystone.log

Using --help says arguments needed are optional.
I used --all option to check and the command was executed successfully. The way I see it is some arguments have been marked optional when they are actually necessary.

It looks like henrynash tried to make this smarter initially: https://github.com/openstack/keystone/blob/master/keystone/cmd/cli.py#L804-L810

We could mark the arguments as required by setting "required=True" to a parser subgroup (https://github.com/openstack/keystone/blob/master/keystone/cmd/cli.py#L784-L799)
