maobaolong commented on HDFS-13204:
-----------------------------------
I think the icon can be replace to others, but it is another thing we should
think about.
The core problem i think is that we should not use the node state style class
in the Subclusters page, we should use the new state style class and we can
replace these icons to new icons to make much sense every time.

> In federation health webpage, the safe mode icons of Subclusters and Routers
> are inconsistent.
> The safe mode icon of Subclusters may induce users the name service is
> maintaining.

> In fact, if the name service is in safe mode, users can't do writing related
> operations. So I think the safe mode icon in Subclusters should be modified,
> which may be more reasonable.
