---------------------------------------
Thanks [[email protected]] for taking care of this. The original change is
relatively new and only introduced in current trunk (so 3.4.0 AFAIK). Its
YARN-10911.

> YARN-10838 and YARN-10911 introduced an unfortunate change in Configuration
> that could potentially be backward incompatible (visibility of
> substituteVars). Since it is easily circumvented, my proposal is to avoid
> breaking changes if possible.
> One found issue is that Oozie defines substituteVars as a private method.
