> Another issue I faced is, on the helix-ui, it can show all resources, but
> when selecting a resource, the "partitions" tab couldn't show which
> instances it be assigned to; the only message is "No partitions of
>  <resource_name> are assigned!"
> I checked the UI code, it indicates the reason is the "listFields" is
> empty. That matches with what I see with the helix-admin.sh
> --listResourceInfo:

> I checked the code, it seems for FULL_AUTO, the values for "listFields" and

> In ResourceStateSpec#getResourceStateTable, we should check the rebalance mode, and use the partitions from external view if FULL_AUTO, as there's no ideal placement for them.
