Summary: LongBufferPoolTest burn test fails assertion Key: CASSANDRA-14790 URL: https://issues.apache.org/jira/browse/CASSANDRA-14790 Project: Cassandra Issue Type: Test Components: Testing Environment: Run under macOS 10.13.6, with patch (attached, but also https://github.com/jonmeredith/cassandra/tree/failing-burn-test) Reporter: Jon Meredith Attachments: 0001-Add-burn-testsome-target-to-build.xml.patch, 0002-Initialize-before-running-LongBufferPoolTest.patch The LongBufferPoolTest from the burn tests fails with an assertion error. I added a build target to run individual burn tests, and \{jasobrown} gave a fix for the uninitialized test setup (attached), however the test now fails on an assertion about recycling buffers.
