> OOZIE-1890 moved all default config values from the code and oozie-site into 
> oozie-default; it also added a WARN message on startup when a config is found 
> in oozie-site that's not defined in oozie-default.  
> However, this can produce some false positives.  In particular, we observed 
> these:
> {noformat}

> SERVER[<redacted>] Invalid configuration defined,

> {noformat}
> While harmful, these messages may be concerning or confusing for users.
> Some of these are simply missing from oozie-default (because they have no 
> default value?), while others such as the ProxyUserService configs, will 
> require special handling because the property name can vary.
