Minor Description
Feel it is a little painful to scroll down every time in order to find a category of properties. Adding an index of content at the beginning of the configuration table maybe helpful in two ways:
1) give users an overview of what can be configured.
2) easy to access one category's properties.
I think the index does not need to be properties level, only need to be categories level, such as "job configuration", "yarn configuration".
Maybe I miss some hidden-awesome feature that is already embedded in that page? I remember criccomini and davidzchen discussed this problem in another ticket but can not find it out.
