Zhijie Shen commented on YARN-3539:
-----------------------------------
bq. The existing compatibility document actually states that the History Server
is a stable REST API, which effectively means that ATSv1 has already been
declared as a stable API.
I think it means *MR* History Server. Though the link is broken here, you can
check the side bar. And {{HistoryServerRest.md}} documented MR JHS APIs. On the
other side, timeline REST APIs have never been documented. I used to have a
patch for YARN-1876. Unfortunately, it was not committed.

> The ATS v2 discussion and YARN-2423 have raised the question: "how stable are
> the ATSv1 APIs"?
> The existing compatibility document actually states that the History Server
> is [a stable REST
> API|http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/Compatibility.html#REST_APIs],
> which effectively means that ATSv1 has already been declared as a stable API.
> Clarify this by patching the compatibility document appropriately
