Jason Lowe commented on YARN-2147:
----------------------------------
The test timeouts were an artifact of a period where we were requiring each
test to have a timeout to work around a surefire timeout bug, but we no longer
need each test to have one. It's not going to hurt if present even for tests
that shouldn't need them as long as the timeout is reasonable for the test.
+1 lgtm. Committing this.

> the client can lack critical details needed to understand the nature of the
> error. Only the message of the error exception is conveyed to the client,
