Gour Saha commented on SLIDER-938:
----------------------------------
One suggestion is to use {{\-\-containers}} instead of {{\-\-id}}. The benefit
is two-fold. One, it maintains consistency with the same option used for
{{slider upgrade}} command. Second, resize-container should support resizing of
multiple containers in a single command as well (assuming all of them needs to
be resized to the same memory and vcores).
Additionally, I would also recommend supporting an option {{\-\-components}}
such that a single command can resize all containers belonging to one (or more)
component(s)/role(s) (say HBASE_REGIONSERVER). This avoids the need to specify
a huge list of containers if they all belong to a single component. This option
is supported by the {{slider upgrade}} command as well.
