Subject [jira] [Commented] (CASSANDRA-10730) periodic timeout errors in dtest
Date Tue, 05 Jan 2016 17:23:39 GMT

Jim Witschey commented on CASSANDRA-10730:
------------------------------------------

Thanks for the feedback. I haven't scraped down CassCI results yet, but I'm made to understand
things are much better now, so we may well let it be, but if we continue, we'll check that
out.

> Dtests often fail with connection timeout errors. For example:
> http://cassci.datastax.com/job/cassandra-3.1_dtest/lastCompletedBuild/testReport/upgrade_tests.cql_tests/TestCQLNodes3RF3/deletion_test/
> {code}
> ('Unable to connect to any servers', {'127.0.0.1': OperationTimedOut('errors=Timed out
creating connection (10 seconds), last_host=None',)})
> {code}
> We've merged a PR to increase timeouts:
> https://github.com/riptano/cassandra-dtest/pull/663
> It doesn't look like this has improved things:
> http://cassci.datastax.com/view/cassandra-3.0/job/cassandra-3.0_dtest/363/testReport/
> Next steps here are
> * to scrape Jenkins history to see if and how the number of tests failing this way has
increased (it feels like it has). From there we can bisect over the dtests, ccm, or C*, depending
on what looks like the source of the problem.
> * to better instrument the dtest/ccm/C* startup process to see why the nodes start but
don't successfully make the CQL port available.
