trouble running Cassandra nosetests
Hi All,
I'm a Cassandra newbie working on getting my sandbox up to speed. Following the instructions on HowToContribute, I've gotten far enough along to be able to run "ant test" without any errors. But "nosetests" is failing, see details below. Looks like the test teardown routine is unhappy because the pid it's trying to kill has already died. Before I get into a detailed dive to figure out what's going wrong, thought I'd check with the community to see if I'm missing something obvious. (Is it easy to run nosetests in the debugger and step through the code?). Thanks,
Walter Gillett
here's the test failure:
$ nosetests -x
E

Thanks - also now I see this debugging tip is covered in the nose documentation. Will add some notes to the wiki on troubleshooting when I get a chance.

Running nose with the following:
nosetests --pdb-failures
should break into pdb, the debugger, on failure so that you can see
what's going on.
I usually see that error if there's a stray Cassandra instance running
(not the one from the system tests or its pid file, just another
instance)

Thanks!!! There was indeed a stale Cassandra process getting in the way. Killed that process and now nosetests runs happily to completion with no errors.
(Moot point now but: I'm running Ubuntu 9.04, Cassandra trunk.)

Are there unkilled cassandra java processes hanging around? Do you
get the same thing if you kill them, r/m the pid, and try again? What
platform is this? What version of cassandra?
