Michael Semb Wever commented on CASSANDRA-11928: ------------------------------------------------ I've been able to reproduce the flakiness of the dtest along all of the trunk since the {{cassandra-3.11}} was branched. This corresponds to the date of when this ticket was reported. Oddly though, we don't see the flakiness in ASF Jenkins anywhere except for against trunk. This could be because Cassandra 4.0 uses more resources per node than previous versions (getting a three node ccm working reliably in tests in circleci/travis/jenkens is considerably harder than it was in Cassandra 3.11 and before). The bisecting i did used the following {{bisect.sh}} script and recipe. The {{bisect.sh}} script: {noformat} #!/bin/bash set -e cd /home/mick/src/apache/cassandra ant realclean ant artifacts cd /home/mick/src/apache/cassandra-dtest/ source ~/dtest/bin/activate # iterate 20 times, making sure this flakey test works on this sha for i in {0..19} ; do echo " ITERATION $i " python -m pytest --cassandra-dir=/home/mick/src/apache/cassandra cql_tracing_test.py done cd /home/mick/src/apache/cassandra git stash {noformat} The execution: {code} git bisect start git bisect bad git bisect good `git log cassandra-3.11..trunk --oneline | tail -1 | cut -d' ' -f1` git bisect run ./bisect.sh {code} > dtest failure in cql_tracing_test.TestCqlTracing.tracing_simple_test > -------------------------------------------------------------------- > > Key: CASSANDRA-11928 > URL: https://issues.apache.org/jira/browse/CASSANDRA-11928 > Project: Cassandra > Issue Type: Bug > Components: Test/dtest > Reporter: Craig Kodman > Priority: Normal > Labels: dtest, flaky > > example failure: > http://cassci.datastax.com/job/cassandra-3.0_dtest/727/testReport/cql_tracing_test/TestCqlTracing/tracing_simple_test > Failed on CassCI build cassandra-3.0_dtest #727 > Is it a problem that the tracing message with the query is missing? -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
