Íñigo Goiri commented on YARN-8348:
-----------------------------------
Technically the null check in AfterClass shouldn't be needed as a failure in
BeforeClass should trigger the error everywhere else.
In any case, is good to not have a NPE if the BeforeClass fails.
So in the output we went from a double NoClassDefFound+NPE to just
NoClassDefFound.
I think this is an improvement but we need to figure out the reason for the
NoClassDefFound (probably a separate JIRA).
The real fix here would be the one in TestHBaseTimelineStorageDomain which
leaves the mini cluster open.
[^YARN-8348.v1.patch] LGTM.
Let's wait for Yetus.
