Subject [jira] [Commented] (CASSANDRA-9902) Windows dtest: invalid jolokia agent path
Date Fri, 31 Jul 2015 19:47:24 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-9902?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14649719#comment-14649719
] 

Paulo Motta commented on CASSANDRA-9902:
----------------------------------------

to make the context clearer, the {{TestConfiguration.change_durable_writes_test}} was failing
because of the following assertion near the end of the test:

{noformat}
self.assertGreater(commitlog_size(node), init_size, msg='ALTER KEYSPACE was not respected')
{noformat}

because the highlighted part from the test description was actually missing from the test:

{noformat}
        - using ALTER KEYSPACE to set its DURABLE_WRITES option to true,
        ***writing a dataset to this keyspace that is known to trigger a commitlog fsync***
        - asserting that the commitlog has grown in size since the data was written.
{noformat}

So I basically add the following missing line before the assertion to make the test pass (in
this [commit|https://github.com/pauloricardomg/cassandra-dtest/commit/dfca2e8918b89bc9b88a2ac4a950699d7a99baaa]):

{noformat}
write_to_trigger_fsync(session, 'ks', 'tab')
{noformat}

Does this seems OK?
