Subject [jira] [Commented] (CASSANDRA-10459) Fix largecolumn_test.py:TestLargeColumn.cleanup_test dtest
Date Wed, 07 Oct 2015 23:36:26 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-10459?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14947805#comment-14947805
] 

Paulo Motta commented on CASSANDRA-10459:
-----------------------------------------

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, 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.
