----------------------------------------
Summary: periodic timeout errors in dtest
Key: CASSANDRA-10730
URL: https://issues.apache.org/jira/browse/CASSANDRA-10730
Project: Cassandra
Issue Type: Bug
Reporter: Jim Witschey
Assignee: Jim Witschey
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.
