Íñigo Goiri commented on HDFS-14917:
------------------------------------
I kind of agree on the first point.
For the second point, this would now be confused with the safe mode icon so I'm
not sure there is a point there.
Keep in mind we also have OBSERVER now from HDFS-14887.
In any case, I agree with the overall direction and I think that we should look
at all these icons holistically.
It might be better to expand the scope of this JIRA to look at all the icons
and see if we can unify all of them.
For example, I think we could even show the icons used in RBF in the main page
for the NN.
Right now, the NN main page has (active)/(standby).
We could start using the icons there.

> This is a really simple UI change proposal:
> The icon of "Decommissioned & dead" datanode could be improved. It can be
> changed from !image-2019-10-21-18-05-19-160.png|width=31,height=28! to
> !image-2019-10-21-18-04-52-405.png|width=32,height=29! so that,
> # icon " !image-2019-10-21-18-13-01-884.png|width=26,height=25! " can be
> used for all status starts with "decommission" on dfshealth.html,
> # icon " !image-2019-10-21-18-13-01-884.png|width=26,height=25! " can be
> differentiated with icon " !image-2019-10-21-18-13-54-427.png! " on
> federationhealth.html
> |*DataNode Infomation Legend (now)*
> dfshealth.html#tab-datanode
> |!image-2019-10-21-17-49-10-635.png|width=516,height=55!|
