Steve Loughran commented on HADOOP-13372:
-----------------------------------------
I like the move; you should go back to assert. It's a bit confusing, but
Assert: any exception fails the test
Assume: throws an AssumptionException which tells JUnit to report it as
skipped. its how we turn off tests which don't run on windows, if the object
endpoint isn't set, etc. Using it will stop failures being picked up.
I see the patch isn't applying. Try creating a patch against branch-2 & name
the patch file, "HADOOP-13372-branch-2-003.patch" to tell yetus which branch to
apply against
