Bikas Saha commented on TEZ-2976:
---------------------------------
lgtm. + 1
Separately, IMO we need to make the TestRecovery avoid random selections. If
the idea is to reduce the test time then its probably not worth it. Instead, we
could separate the cases into core and full sets such that core runs always and
full can be run manually to verify recovery in more detail.
