Subject [jira] [Commented] (CASSANDRA-9764) dtest for many UPDATE batches, low contention fails on trunk
Date Mon, 27 Jul 2015 21:17:04 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-9764?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14643413#comment-14643413
] 

Jim Witschey commented on CASSANDRA-9764:
-----------------------------------------

Nope -- the test passes now.

I'll close the ticket, but we can't run the test in regular CassCI builds because periodically
hangs there ([example CaccCI run|http://cassci.datastax.com/job/trunk_dtest-skipped-with-require/10/consoleFull]).
I've filed [an issue on the dtest repo|https://github.com/riptano/cassandra-dtest/issues/421]
to track progress on the hanging test.

> {{paxos_tests.py:TestPaxos.contention_test_multi_iterations}} fails consistently on trunk
([cassci history|http://cassci.datastax.com/view/trunk/job/trunk_dtest/lastSuccessfulBuild/testReport/paxos_tests/TestPaxos/contention_test_multi_iterations/history/]).
The test works by creating 8 workers, each of which increments an integer 100 times using
UPDATE. Based on the test failures, it looks like 2 or 3 of the updates are consistently dropped.
Other dtests that don't run as many iterations but have more contention succeed.
> I'm assigning you, [~slebresne], because you wrote the test and were the last person
to modify it, but feel free to reassign. Thanks!
