Subject [jira] [Commented] (CASSANDRA-10938) test_bulk_round_trip_blogposts is failing occasionally
Date Mon, 01 Feb 2016 07:54:39 GMT


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|].

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|] is its own patch,
the [2.2 patch|] 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|].
