mahout-0.2 release test case failed
Thanks again, Sean! We run Maven on linux and this time we only got one test failed. It is a clustering test. The error message is included below. Has anybody else run into the same error before?
Thanks

Is it by any chance due to OutOfMemoryError? then just set
MAVEN_OPTS=-Xmx512m before running mvn.

James,
I haven't run into the problem, but if you want to try the build without the
unit tests, you can run
mvn clean install -DskipTests=true

Thanks, Sean. I run it again, and the error is reproducible as I got exactly the same error.
Thanks,
James

That's odd, I'm sure the tests passed at time of release since we
couldn't proceed without it.
I *think* you can more or less safely ignore it, but, wondering at the
difference. It could be due to some differences in random number
generation -- which would be a bug since the unit tests ought to use
the same RNG each time. Is it reproducible?
I don't see this in head, FWIW.
