> Bugs that occur when server stops sending some command or config parameter (for example, due to xml configs changes) are extremely hard to detect if we use something like hdp_default.
> In RMF, this issue is partially fixed (we fail fast  on first usage of iundefined parameter), but it is not the case when using J2.
> Also now default is not really suitable since configurations json can be really different.
