Subject [jira] [Created] (CASSANDRA-3727) Fix unit tests failure
Date Wed, 11 Jan 2012 09:40:39 GMT
Fix unit tests failure
----------------------

                 Key: CASSANDRA-3727
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-3727
             Project: Cassandra
          Issue Type: Bug
          Components: Tests
    Affects Versions: 1.0.7
            Reporter: Sylvain Lebresne
            Priority: Blocker
             Fix For: 1.0.7


On current 1.0 branch (and on my machine: Linux), I have the following unit test failures:
* CliTest and EmbeddedCassandraTest: they both first kind of pass (JUnit first prints a message
with no failures in it), then hang until JUnit timeout and fails with a 'Timeout occurred'.
In other word, the tests themselves are passing, but something they do prevents the process
to exit cleanly leading to a JUnit timeout. I don't want to discard that as not a problem,
because if something can make the process not exit cleanly, this can be a pain for restarts
(and in particular upgrades) and hence would be basically a regression. I'm marking the ticket
as blocker (for the release of 1.0.7) mostly because of this one.
* SystemTableTest: throws an assertionError. I haven't checked yet, so that could be an easy
one to fix.
* RemoveTest: it fails, saying that '/127.0.0.1:7010 is in use by another process' (consistently).
But I have no other process running on port 7010. It's likely just of problem of the test,
but it's new and in the meantime removes are not tested.
* I also see a bunch of stack trace with errors like:
{noformat}
    [junit] ERROR 10:01:59,007 Fatal exception in thread Thread[NonPeriodicTasks:1,5,main]
    [junit] java.lang.RuntimeException: java.io.IOException: Unable to create hard link from
build/test/cassandra/data/Keyspace1/Indexed1-hc-1-Index.db to /home/mcmanus/Git/cassandra/build/test/cassandra/data/Keyspace1/backups/Indexed1-hc-1-Index.db
(errno 17)
{noformat}
(with SSTableReaderTest). This does not make the tests fail, but it is still worth investigating.
It may be due to CASSANDRA-3101.
