Yep, that CatalogManagerAddsNonVoter is the new one which was
committed just yesterday.

The raft_consensus_nonvoter-itest is the set of tests added for 3-4-3
re-replication improvements. I'm adding more scenarios there right
now, and I'll take care of the current flaky ones from there as well.
Thanks,
Alexey

N/w! I should have checked with you beforehand given you were
already in
the area (per your response last week). Seems the double-effort was
fairly
minimal anyway.
With the fixes for tablet_copy-itest and delete_table-itest checked
in, the
next-highest offenders on the dashboard
<http://dist-test.cloudera.org:8080/> are:
- raft_consensus_nonvoter-itest (9.62%)
- linked_list-test (8.45%)
From a quick glance I'm not sure I have a grasp on what's going on in
either test. Would anyone like to volunteer? 😃

I just realized after re-reading this message that Andrew was about to
look at the flake in delete_table-itest as well. I'm sorry for the
double-effort here, if any. I read this message after posting the
patch.

review for one flake there for a long time).
BTW, it would be much better if it were possible to see the type of
failed
build in the dashboard (as it was prior to quasar). Is the type
of a
build
something inherently impossible to expose from quasar?
I think it should be possible by just setting the BUILD_ID
environment
variable appropriate before reporting the test result. That
information
should be available in the enviornment as $BUILD_TYPE or somesuch. I
think
Ed is out this week but maybe he can take a look at this when he
gets
back?

Hey folks,
It seems some of our tests have gotten pretty flaky lately
again. Some
of
it is likely due to churn in test infrastructure (running on a
different
VM
type now I think) but it makes me a little nervous to go into
the 1.6
release with some tests at 5%+ flaky.
Can we get some volunteers to triage the top couple most flaky?
Note
that
"triage" doesn't necessarily mean "fix" -- just want to
investigate to
the
point that we can decide it's likely to be a test issue or known
existing
issue rather than a regression before the release.
I'll volunteer to look at consensus_peers-itests (the top most
flaky
one).
