CSIT test Local_Leader_Shutdown fails in ask mode

Bug Medium Resolved Won't Do Tom Pantelis Josh Hershberg Thu, 2 Aug 2018 11:52:23 +0000 Mon, 6 Aug 2018 06:12:29 +0000 Mon, 6 Aug 2018 06:12:29 +0000 Fluorine Neon clustering 0 2 <p>Attached please find:</p> <p>log.html.gz of the sandbox CSIT run</p> <p>odl<span class="error">&#91;1-3&#93;</span>.log - the karaf logs of that specific test.</p> <p>For "5. odl1 does NOT receive the LeaderStateChanged event", I would expect that since the shard was removed in step 2. For transactions in flight, with ask-based, it is expected that they may fail. This is primarily what tell-based is designed to alleviate. I assume the test passes with tell-based which I assume is why it only runs with tell-based.</p> <p>So I don't think there's any bug here, except for the known limitation with ask-based - unless I'm missing something....</p> <p> </p> <p> </p> <p>Yes, I <b>thought</b> this was the case but wanted to make sure. Thanks.</p> <p>See the comment from Tom P.</p> Relates CONTROLLER-1786 OVSDB-434 NETVIRT-1315 Development Epic Link NETVIRT-996 Rank 0|i03hl3:
