Wangda Tan commented on YARN-8466:
----------------------------------
Thanks [~cheersyang], actually this JIRA is inspired by the distributed chaos
monkey framework mentioned by you offline.
For the UT-like binary, the benefit is we can really run smoke test in a
self-contained way. W/o any env setup, we can do sanity test in minutes. And
the mock framework allows to start/stop app/node really fast.
And I can definitely see the value of distributed chaos monkey framework. If we
can make the test can easily run, it will be super useful to run before any
releases!
[~sunilg],
To me, the UT is not necessarily to use the same code base of the distributed
one (of course, ideally share the same one, but in practice it could be hard).
