Steve Loughran commented on HADOOP-9330:
----------------------------------------

hey,. thank you for reviewing my work. Now, I have a few more. Why not start with YARN-679,
which is trying to do a robust service launcher to replace the pool of different ones we have
today?

> HADOOP-9112 has added a requirement for all new test methods to declare a timeout, so
that jenkins/maven builds will have better information on a timeout.
> Hard coding timeouts into tests is dangerous as it will generate spurious failures on
slower machines/networks and when debugging a test.
> I propose providing a custom JUnit4 test runner that test cases can declare as their
test runner; this can provide timeouts specified at run-time, rather than in-source.
