Mikhail Efremov updated IGNITE-26459:
-------------------------------------
Description:
*Description*
The main goal is to create a new CLI method (follow the
[guidance|https://github.com/apache/ignite-3/blob/main/modules/cli/README.md]).
The current approved command is {{cluster zone datanodes recalculate}} and the
command should accept a list of zone names to recalculate data nodes for. The
call should use new REST POST method for data nodes recalculation from
IGNITE-26544. The corresponding CLI tests should be provided.
*Motivation*
In case of scaleUp/Down disabled the only way to adjust dataNodes and thus
recalculate assignments is to alter zone filter. Despite the fact that it works
we need a more user-friendly way to do this. Meaning that we need new CLI
command within 'distribution' group. We already implemented REST API module
that we can reuse with {{*Api}} object through {{ApiClientFactory#getClient}}.
*Definition of done*
# New CLI commands are created with the list of zone names as the argument to
call.
# CLI tests for the new method.

*Description*
The main goal is to create a new POST method in REST API module (follow the
[guidance|https://github.com/apache/ignite-3/blob/main/modules/rest/README.md]).
The current approved URI is
{{/management/v1/cluster/zone/datanodes/recalculate}} and the method should
accept a list of zone names to recalculate data nodes for. The controller
should use new public method for data nodes recalculation from IGNITE-26543.
The corresponding REST API tests should be provided.
*Motivation*
In case of scaleUp/Down disabled the only way to adjust dataNodes and thus
recalculate assignments is to alter zone filter. Despite the fact that it works
we need a more user-friendly way to do this. Meaning that we need new CLI

*Definition of done*
# Possibly new controller for {{zone/datanodes}} commands is created.
# New POST method with the list of zone names as the argument to call.
# REST API tests for the new method.
or overloading already existing 'reset'.
DZM internal changes should be pretty trivial - effectively it's the same as
altering filter, but we need to keep compatibility aspects in mind.
