Hello all, 
I’m trying to execute some unit tests and I’m getting the following errors which are unrelated to my changes.  Does anyone have any suggestions?
Thanks,

Re: Unit Tests Failing

Posted by Kunal Khatua <ku...@apache.org>.
I recall seeing something like this a week ago, I think. I don't recall if I had to do anything specific to fix it. Are you rebased on the latest master?
