Daniel Templeton commented on YARN-7505:
----------------------------------------
The most correct approach is to rev the endpoint version to v2 and leave all
the broken stuff in v1, but the REST code was not written to make that easy.
It would be a pretty big refactor. My angle here is that since the APIs are
currently broken, fixing them should be OK, even though it's incompatible.
Because they're broken. No JSON parser will handle the output correctly. The
only client who could be consuming them are either parsing the JSON by hand or
just pattern matcher for the bits and pieces they need.

> For all endpoints that return DAOs that contain maps, the generated JSON is
> malformed. For example:
