> Issue Type: Improvement
> Reporter: Alex Juncevich
> Assignee: Alex Juncevich
> Priority: Major
>
> Need to add additional information in rebalancing status cli command.
> # Rebalancing start time
> # Rebalancing parameters
> # How many containers need to be balanced and how many containers from then
> still unbalanced
> # How many data in Gb need to transfered in general and how many
> untransfered yet
> # Which datanodes took a part in rebalancing
> As idea to use flags for command to get more information about rebalancing
> status. For example use `-v` or `--verbose`.
