The same issue occurs for Yarn if the following parameters are not filled. Again they do not show up unless explicitly specified.

yarn.resourcemanager.zk-address 
and
hadoop.registry.zk.quorum

>          Issue Type: Improvement
>    Affects Versions: 1.7.0
>            Reporter: Taeyun Kim
>            Priority: Minor

> After YARN Configs is changed and saved, there is a case that the saved configuration itself bacomes invalid state(for example, some config value is missing).
> In my case, the missing one was 'yarn.resourcemanager.fs.state-store.uri'. But that variable is hidden in the folded 'Advanced yarn-site' group, so there is no clue that some variable has incorrect or missing value.
> So when I change an another config value, Discard button is enabled, but Save button is not enabled. But I see no clue why.
> Here, there are 2 problems:
> 1. Incorrect state is saved by UI. It should not happen.
> 2. Sometimes it's hard to see what is wrong that's preventing Save.
> So, at least for the 2nd problem, it would be nice to show what is wrong.
