Subject [jira] [Comment Edited] (CASSANDRA-10459) Fix largecolumn_test.py:TestLargeColumn.cleanup_test dtest

-------------------------------------------------------------------

The test was checking if total off-heap memory usage since node start was below the large
column size (66060288 bytes), and it was passing on cassandra 2.2. However, on 3.0 it was
not passing (probably due to increase in off-heap memory footprint), so I modified the test
to check the memory usage delta instead (before and after stress), which should be sufficient
to identify if heap usage grows proportional to column size.

mind reviewing, [~aweisberg]? Thanks.

> This test on large columns is failing:
> http://cassci.datastax.com/job/cassandra-3.0_dtest/lastCompletedBuild/testReport/largecolumn_test/TestLargeColumn/cleanup_test/
> and it's been failing for a while:
> http://cassci.datastax.com/job/cassandra-3.0_dtest/lastCompletedBuild/testReport/junit/largecolumn_test/TestLargeColumn/cleanup_test/history/
> I've reproduced the failure on OpenStack, so it's not just a CassCI problem.
