Subject Re: Current master broken?
Date Sun, 15 Mar 2015 16:04:53 GMT
I think the issue is that our tests are executed on travis machines with
different physical CPU core counts.

I've pushed a 5 days old commit (
https://github.com/rmetzger/flink/commit/b4e8350f52c81704ffc726a1689bb0dc7180776d)
to travis, and it also failed with that issue:
https://travis-ci.org/rmetzger/flink/builds/54443951

Thanks for resolving the issue so quickly Stephan!
