Stefania commented on CASSANDRA-10938:
--------------------------------------
I'm not surprised you couldn't reproduce with JFR enabled.
I've fixed the consistency level for {{test_bulk_round_trip_blogposts}} and
I've hardened {{test_bulk_round_trip_blogposts_with_max_connections}} by
increasing number of attempts and decreasing number of processes for COPY FROM.
See commit
[here|https://github.com/stef1927/cassandra-dtest/commit/d709b30290049fae37db91b1cc208590b10477f0].
I've run both tests 10 times on Linux and 10 times on Windows without failures.
If you also cannot reproduce I agree with the proposal to commit and monitor on
Jenkins.
Commit information:
* The [2.1 patch|https://github.com/stef1927/cassandra/commits/10938-2.1] is
its own patch, the [2.2
patch|https://github.com/stef1927/cassandra/commits/10938-2.2] is identical to
the 2.1 patch except for a conflict with the imports and it applies cleanly
upwards.
* Pull request for test code is
[here|https://github.com/riptano/cassandra-dtest/pull/776].
