Subject [jira] [Commented] (CASSANDRA-3727) Fix unit tests failure
Date Wed, 11 Jan 2012 10:11:44 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-3727?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13183960#comment-13183960

Pavel Yaskevich commented on CASSANDRA-3727:
--------------------------------------------

I'm saying that it's likely source of the problem and for CliTest fix would be pretty straightforward,
make CliMain to disconnect properly after tests are done (I'm going to attach a patch fixing
patch in a few minutes to this ticket), I don't know about other tests tho.

> 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.
