Stefan Miklosovic commented on CASSANDRA-17397:
-----------------------------------------------
They dont seem to be correlated. I have looked at few of them already and it is
mostly about timeouts.
Not sure if it is reliable info but I built some branch on top of current trunk
today and I got like 11 failures only, mostly notoric ones related to upgrades

> cleanup cqlshlib unit test failures and warnings
> ------------------------------------------------
>
> Key: CASSANDRA-17397
> URL: https://issues.apache.org/jira/browse/CASSANDRA-17397
> Project: Cassandra
> Issue Type: Bug
> Components: CQL/Interpreter
> Reporter: Brad Schoening
> Assignee: Brad Schoening
> Priority: Normal
> Fix For: 4.1
>
>
> The cqlshlib unit tests have some regular failures and warnings.
> # test_copyutil.py fails with too many open files when ulimit is 256
> # cassconnect.py:39: DeprecationWarning: Legacy execution parameters
> # sslhandling.py:42: DeprecationWarning: The SafeConfigParser class has been
> renamed to ConfigParser
> # remove unused reference to nosetests.xml in Jenkinsfile
>
> The cqlshlib test test_copyutil.py fails on MacOS with
> *E OSError: [Errno 24] Too many open files*
> This happens because the test does not close the file descriptors after use.
> The default ulimit on MacOS is small, 256:
> % ulimit -n
> 256
> The simple fix is to close the pipe after use. Increasing ulimit nofiles
> works also, but shouldn't be necessary.
